Pull core block IO changes from Jens Axboe: "The major piece in here is the immutable bio_ve series from Kent, the rest is fairly minor. It was supposed to go in last round, but various issues pushed it to this release instead. The pull request contains: - Various smaller blk-mq fixes from different folks.

Chris Mason reported a NULL pointer derefernence in generic_getxattr() that was due to sb->s_xattr being NULL. The reason is that the nfs #ifdef's for ACL support were misplaced, and the nfs3 inode operations had the xattr operation pointers set up, even though xattrs were not actually supported. As a result, the xattr code was being called without the infrastructure having been set up. Move the #ifdef's appropriately.

Commit 0abdd7a8 ("dma-debug: introduce debug_dma_assert_idle()") was reworked to expand the overlap counter to the full range expressable by 3 tag bits, but it has a thinko in treating the overlap counter as a pure reference count for the entry. Instead of deleting when the reference-count drops to zero, we need to delete when the overlap-count drops below zero. Also, when detecting overflow we can just test the overlap-count > MAX rather than applying special meaning to 0. Regression report available here: http://marc.info/?l=linux-netdev&m=139073373932386&w=2 This patch, now tested on the original net_dma case, sees the expected handful of reports before the eventual data corruption occurs.

Commit 63d0f0a3 ("mm/readahead.c:do_readhead(): don't check for ->readpage") unintentionally made do_readahead return 0 for all valid files regardless of whether readahead was supported, rather than the expected -EINVAL. This gets forwarded on to userspace, and results in sys_readahead appearing to succeed in cases that don't make sense (e.g. when called on pipes or sockets). This issue is detected by the LTP readahead01 testcase. As the exact return value of force_page_cache_readahead is currently never used, we can simplify it to return only 0 or -EINVAL (when readpage or readpages is missing). With that in place we can simply forward on the return value of force_page_cache_readahead in do_readahead. This patch performs said change, restoring the expected semantics.

Commit 309381fe ("mm: dump page when hitting a VM_BUG_ON using VM_BUG_ON_PAGE") added a bunch of VM_BUG_ON_PAGE() calls. But, most of the ones in the slub code are for _temporary_ 'struct page's which are declared on the stack and likely have lots of gunk in them. Dumping their contents out will just confuse folks looking at bad_page() output. Plus, if we try to page_to_pfn() on them or soemthing, we'll probably oops anyway. Turn them back in to VM_BUG_ON()s.

On kmem_cache_create_memcg() error path we set 'err', but leave 's' (the new cache ptr) undefined. The latter can be NULL if we could not allocate the cache, or pointing to a freed area if we failed somewhere later while trying to initialize it. Initially we checked 'err' immediately before exiting the function and returned NULL if it was set ignoring the value of 's': out_unlock: ... if (err) { /* report error */ return NULL; } return s; Recently this check was, in fact, broken by commit f717eb3a ("slab: do not panic if we fail to create memcg cache"), which turned it to: out_unlock: ... if (err && !memcg) { /* report error */ return NULL; } return s; As a result, if we are failing creating a cache for a memcg, we will skip the check and return 's' that can contain crap. Obviously, commit f717eb3a intended not to return crap on error allocating a cache for a memcg, but only to remove the error reporting in this case, so the check should look like this: out_unlock: ... if (err) { if (!memcg) return NULL; /* report error */ return NULL; } return s; [rientjes@google.com: despaghettification] [vdavydov@parallels.com: patch monkeying] Signed-off-by: NDavid Rientjes <rientjes@google.com> Signed-off-by: NVladimir Davydov <vdavydov@parallels.com> Signed-off-by: NDave Jones <davej@redhat.com> Reported-by: NDave Jones <davej@redhat.com> Acked-by: NPekka Enberg <penberg@kernel.org> Cc: Christoph Lameter <cl@linux.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Change parameter types of s390's compat ipc syscall from unsigned long to compat_ulong_t to enforce zero extension of these parameters. This is not really a bug, since s390_ipc compat syscall is only a wrapper to the generic compat_sys_ipc() syscall, which performs correct zero and sign extension. This was introduced with commit 56e41d3c ("merge compat sys_ipc instances").

Commit d5dc77bf ("consolidate compat lookup_dcookie()") coverted all architectures to the new compat_sys_lookup_dcookie() syscall. The "len" paramater of the new compat syscall must have the type compat_size_t in order to enforce zero extension for architectures where the ABI requires that the caller of a function performed zero and/or sign extension to 64 bit of all parameters.

We got a report that the pwritev syscall does not work correctly in compat mode on s390. It turned out that with commit 72ec3516 ("switch compat readv/writev variants to COMPAT_SYSCALL_DEFINE") we lost the zero extension of a couple of syscall parameters because the some parameter types haven't been converted from unsigned long to compat_ulong_t. This is needed for architectures where the ABI requires that the caller of a function performed zero and/or sign extension to 64 bit of all parameters.

The command line parsing takes place before jump labels are initialised which generates a warning if numa_balancing= is specified and CONFIG_JUMP_LABEL is set. On older kernels before commit c4b2c0c5 ("static_key: WARN on usage before jump_label_init was called") the kernel would have crashed.

The VM is currently heavily tuned to avoid swapping. Whether that is good or bad is a separate discussion, but as long as the VM won't swap to make room for dirty cache, we can not consider anonymous pages when calculating the amount of dirtyable memory, the baseline to which dirty_background_ratio and dirty_ratio are applied. A simple workload that occupies a significant size (40+%, depending on memory layout, storage speeds etc.) of memory with anon/tmpfs pages and uses the remainder for a streaming writer demonstrates this problem. In that case, the actual cache pages are a small fraction of what is considered dirtyable overall, which results in an relatively large portion of the cache pages to be dirtied. As kswapd starts rotating these, random tasks enter direct reclaim and stall on IO. Only consider free pages and file pages dirtyable.

Tejun reported stuttering and latency spikes on a system where random tasks would enter direct reclaim and get stuck on dirty pages. Around 50% of memory was occupied by tmpfs backed by an SSD, and another disk (rotating) was reading and writing at max speed to shrink a partition. : The problem was pretty ridiculous. It's a 8gig machine w/ one ssd and 10k : rpm harddrive and I could reliably reproduce constant stuttering every : several seconds for as long as buffered IO was going on on the hard drive : either with tmpfs occupying somewhere above 4gig or a test program which : allocates about the same amount of anon memory. Although swap usage was : zero, turning off swap also made the problem go away too. : : The trigger conditions seem quite plausible - high anon memory usage w/ : heavy buffered IO and swap configured - and it's highly likely that this : is happening in the wild too. (this can happen with copying large files : to usb sticks too, right?) This patch (of 2): The dirty_balance_reserve is an approximation of the fraction of free pages that the page allocator does not make available for page cache allocations. As a result, it has to be taken into account when calculating the amount of "dirtyable memory", the baseline to which dirty_background_ratio and dirty_ratio are applied. However, currently the reserve is subtracted from the sum of free and reclaimable pages, which is non-sensical and leads to erroneous results when the system is dominated by unreclaimable pages and the dirty_balance_reserve is bigger than free+reclaimable. In that case, at least the already allocated cache should be considered dirtyable. Fix the calculation by subtracting the reserve from the amount of free pages, then adding the reclaimable pages on top.

Prior to commit fe35004f ("mm: avoid swapping out with swappiness==0") setting swappiness to 0, reclaim code could still evict recently used user anonymous memory to swap even though there is a significant amount of RAM used for page cache. The behaviour of setting swappiness to 0 has since changed. When set, the reclaim code does not initiate swap until the amount of free pages and file-backed pages, is less than the high water mark in a zone. Let's update the documentation to reflect this.
