Currently flags for extent status tree are defined twice, once shifted and once without a being shifted. Consolidate these definitions into one place and make some computations automatic to make adding flags less error prone. Compiler should be clever enough to figure out these are constants and generate the same code. Signed-off-by: NJan Kara <jack@suse.cz> Signed-off-by: NTheodore Ts'o <tytso@mit.edu>

Currently we scan extent status trees of inodes until we reclaim nr_to_scan extents. This can however require a lot of scanning when there are lots of delayed extents (as those cannot be reclaimed). Change shrinker to work as shrinkers are supposed to and *scan* only nr_to_scan extents regardless of how many extents did we actually reclaim. We however need to be careful and avoid scanning each status tree from the beginning - that could lead to a situation where we would not be able to reclaim anything at all when first nr_to_scan extents in the tree are always unreclaimable. We remember with each inode offset where we stopped scanning and continue from there when we next come across the inode. Note that we also need to update places calling __es_shrink() manually to pass reasonable nr_to_scan to have a chance of reclaiming anything and not just 1.

Currently callers adding extents to extent status tree were responsible for adding the inode to the list of inodes with freeable extents. This is error prone and puts list handling in unnecessarily many places. Just add inode to the list automatically when the first non-delay extent is added to the tree and remove inode from the list when the last non-delay extent is removed.

In this commit we discard the lru algorithm for inodes with extent status tree because it takes significant effort to maintain a lru list in extent status tree shrinker and the shrinker can take a long time to scan this lru list in order to reclaim some objects. We replace the lru ordering with a simple round-robin. After that we never need to keep a lru list. That means that the list needn't be sorted if the shrinker can not reclaim any objects in the first round.

Currently extent status tree doesn't cache extent hole when a write looks up in extent tree to make sure whether a block has been allocated or not. In this case, we don't put extent hole in extent cache because later this extent might be removed and a new delayed extent might be added back. But it will cause a defect when we do a lot of writes. If we don't put extent hole in extent cache, the following writes also need to access extent tree to look at whether or not a block has been allocated. It brings a cache miss. This commit fixes this defect. Also if the inode doesn't have any extent, this extent hole will be cached as well.

For bigalloc filesystems we have to check whether newly requested inode block isn't already part of a cluster for which we already have delayed allocation reservation. This check happens in ext4_ext_map_blocks() and that function sets EXT4_MAP_FROM_CLUSTER if that's the case. However if ext4_da_map_blocks() finds in extent cache information about the block, we don't call into ext4_ext_map_blocks() and thus we always end up getting new reservation even if the space for cluster is already reserved. This results in overreservation and premature ENOSPC reports. Fix the problem by checking for existing cluster reservation already in ext4_da_map_blocks(). That simplifies the logic and actually allows us to get rid of the EXT4_MAP_FROM_CLUSTER flag completely. Signed-off-by: NJan Kara <jack@suse.cz> Signed-off-by: NTheodore Ts'o <tytso@mit.edu>

ext4_ext_remove_space() can incorrectly free a partial_cluster if EAGAIN is encountered while truncating or punching. Extent removal should be retried in this case. It also fails to free a partial cluster when the punched region begins at the start of a file on that unaligned cluster and where the entire file has not been punched. Remove the requirement that all blocks in the file must have been freed in order to free the partial cluster.

The fix in commit ad6599ab ("ext4: fix premature freeing of partial clusters split across leaf blocks"), intended to avoid dereferencing an invalid extent pointer when determining whether a partial cluster should be freed, wasn't quite good enough. Assure that at least one extent remains at the start of the leaf once the hole has been punched. Otherwise, the pointer to the extent to the right of the hole will be invalid and a partial cluster will be incorrectly freed. Set partial_cluster to 0 when we can tell we've hit the left edge of the punched region within the leaf. This prevents incorrect freeing of a partial cluster when ext4_ext_rm_leaf is called one last time during extent tree traversal after the punched region has been removed. Adjust comments to reflect code changes and a correction. Remove a bit of dead code. Signed-off-by: NEric Whitney <enwlinux@gmail.com> Signed-off-by: NTheodore Ts'o <tytso@mit.edu>

由 Eric Whitney 提交于
The partial_cluster variable is not always initialized correctly when hole punching on bigalloc file systems. Although commit c0634493 ("ext4: fix partial cluster handling for bigalloc file systems") addressed the case where the right edge of the punched region and the next extent to its right were within the same leaf, it didn't handle the case where the next extent to its right is in the next leaf. This causes xfstest generic/300 to fail. Fix this by replacing the code in c0634493922 with a more general solution that can continue the search for the first cluster to the right of the punched region into the next leaf if present. If found, partial_cluster is initialized to this cluster's negative value. There's no need to determine if that cluster is actually shared; we simply record it so its blocks won't be freed in the event it does happen to be shared. Also, minimize the burden on non-bigalloc file systems with some minor code simplification. Signed-off-by: NEric Whitney <enwlinux@gmail.com> Signed-off-by: NTheodore Ts'o <tytso@mit.edu>

Xiaoguang Wang has reported sporadic EBUSY failures of ext4/302 Unfortunetly there is nothing we can do if some other task holds BH's refenrence. So we must return EBUSY in this case. But we can try kicking the journal to see if the other task releases the bh reference after the commit is complete.

In order to access the shadow VMCS, we need to load it. At this point, vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If we now get preempted by Linux, vmx_vcpu_put and, on return, the vmx_vcpu_load will work against the wrong vmcs. That can cause copy_shadow_to_vmcs12 to corrupt the vmcs12 state. Fix the issue by disabling preemption during the copy operation. copy_vmcs12_to_shadow is safe from this issue as it is executed by vmx_vcpu_run when preemption is already disabled before vmentry. This bug is exposed by running Jailhouse within KVM on CPUs with shadow VMCS support. Jailhouse never expects an interrupt pending vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12 is preempted, the active VMCS happens to have the virtual interrupt pending flag set in the CPU-based execution controls.

Specifics: - Fix a crash on r8a7791/koelsch during resume from system suspend caused by a recent cpufreq-dt commit (Geert Uytterhoeven). - Fix an MFD enumeration problem introduced by a recent commit adding ACPI support to the MFD subsystem that exposed a weakness in the ACPI core causing ACPI enumeration to be applied to all devices associated with one ACPI companion object, although it should be used for one of them only (Mika Westerberg). - Fix an ACPI EC regression introduced during the 3.17 cycle causing some Samsung laptops to misbehave as a result of a workaround targeted at some Acer machines. That includes a revert of a commit that went too far and a quirk for the Acer machines in question. From Lv Zheng. - Fix a regression in the system suspend error code path introduced during the 3.15 cycle that causes it to fail to take errors from asychronous execution of "late" suspend callbacks into account (Imre Deak). - Fix a long-standing bug in the hibernation resume error code path that fails to roll back everything correcty on "freeze" callback errors and leaves some devices in a "suspended" state causing more breakage to happen subsequently (Imre Deak). - Make the cpufreq-dt driver disable operation performance points that are not supported by the VR connected to the CPU voltage plane with acceptable tolerance instead of constantly failing voltage scaling later on (Lucas Stach)" * tag 'pm+acpi-3.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / EC: Fix regression due to conflicting firmware behavior between Samsung and Acer. Revert "ACPI / EC: Add support to disallow QR_EC to be issued before completing previous QR_EC" cpufreq: cpufreq-dt: Restore default cpumask_setall(policy->cpus) PM / Sleep: fix recovery during resuming from hibernation PM / Sleep: fix async suspend_late/freeze_late error handling ACPI: Use ACPI companion to match only the first physical device cpufreq: cpufreq-dt: disable unsupported OPPs

Pull PCI fixes from Bjorn Helgaas: "These changes, intended for v3.18, fix: Sysfs - Fix "enable" filename change (Greg Kroah-Hartman) An unintentional sysfs filename change in commit 5136b2da ("PCI: convert bus code to use dev_groups"), which appeared in v3.13, changed "enable" to "enabled", and this changes it back. Old users of "enable" are currently broken and will be helped by this change. Anything that started to use "enabled" after v3.13 will be broken by this change. If necessary, we can add a symlink to make both work, but this patch doesn't do that. PCI device hotplug - Revert duplicate merge (Kamal Mostafa) A mistaken duplicate merge that added a check twice. Nothing's broken; this just removes the unnecessary code. Freescale i.MX6 - Wait for clocks to stabilize after ref_en (Richard Zhu) An i.MX6 clock problem that prevents mx6 nitrogen boards from booting" * tag 'pci-v3.18-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: PCI: Rename sysfs 'enabled' file back to 'enable' PCI: imx6: Wait for clocks to stabilize after ref_en Revert duplicate "PCI: pciehp: Prevent NULL dereference during probe"

Rusty noticed a Really Bad Bug (tm) in my NT fix. The entry code reads out of bounds, causing the NT fix to be unreliable. But, and this is much, much worse, if your stack is somehow just below the top of the direct map (or a hole), you read out of bounds and crash. Excerpt from the crash: [ 1.129513] RSP: 0018:ffff88001da4bf88 EFLAGS: 00010296 2b:* f7 84 24 90 00 00 00 testl $0x4000,0x90(%rsp) That read is deterministically above the top of the stack. I thought I even single-stepped through this code when I wrote it to check the offset, but I clearly screwed it up.
