Pull btrfs update from Chris Mason: "The biggest feature in the pull is the new (and still experimental) raid56 code that David Woodhouse started long ago. I'm still working on the parity logging setup that will avoid inconsistent parity after a crash, so this is only for testing right now. But, I'd really like to get it out to a broader audience to hammer out any performance issues or other problems. scrub does not yet correct errors on raid5/6 either. Josef has another pass at fsync performance. The big change here is to combine waiting for metadata with waiting for data, which is a big latency win. It is also step one toward using atomics from the hardware during a commit. Mark Fasheh has a new way to use btrfs send/receive to send only the metadata changes. SUSE is using this to make snapper more efficient at finding changes between snapshosts. Snapshot-aware defrag is also included. Otherwise we have a large number of fixes and cleanups.

So far we silently ignored when quota mount options were set while quota feature was enabled. But this can create confusion in userspace when mount options are set but silently ignored and also creates opportunities for bugs when we don't properly test all quota types. Actually ext4_mark_dquot_dirty() forgets to test for quota feature so it was dependent on journaled quota options being set. OTOH ext4_orphan_cleanup() tries to enable journaled quota when quota options are specified which is wrong when quota feature is enabled.

Need to consider sequence is: numaq, srat, amd, dummy. and make fall back path working. 2. simply split acpi_numa_init to early_parse_srat. a. that early_parse_srat is NOT called for ia64, so you break ia64. b. for (i = 0; i < MAX_LOCAL_APIC; i++) set_apicid_to_node(i, NUMA_NO_NODE) still left in numa_init. So it will just clear result from early_parse_srat. it should be moved before that.... c. it breaks ACPI_TABLE_OVERIDE...as the acpi table scan is moved early before override from INITRD is settled. 3. that patch TITLE is total misleading, there is NO x86 in the title, but it changes critical x86 code. It caused x86 guys did not pay attention to find the problem early. Those patches really should be routed via tip/x86/mm. 4. after that commit, following range can not use movable ram: a. real_mode code.... well..funny, legacy Node0 [0,1M) could be hot-removed? b. initrd... it will be freed after booting, so it could be on movable... c. crashkernel for kdump...: looks like we can not put kdump kernel above 4G anymore. d. init_mem_mapping: can not put page table high anymore. e. initmem_init: vmemmap can not be high local node anymore. That is not good. If node is hotplugable, the mem related range like page table and vmemmap could be on the that node without problem and should be on that node. We have workaround patch that could fix some problems, but some can not be fixed. So just remove that offending commit and related ones including: f7210e6c ("mm/memblock.c: use CONFIG_HAVE_MEMBLOCK_NODE_MAP to protect movablecore_map in memblock_overlaps_region().") 01a178a9 ("acpi, memory-hotplug: support getting hotplug info from SRAT") 27168d38 ("acpi, memory-hotplug: extend movablemem_map ranges to the end of node") e8d19552 ("acpi, memory-hotplug: parse SRAT before memblock is ready") fb06bc8e ("page_alloc: bootmem limit with movablecore_map") 42f47e27 ("page_alloc: make movablemem_map have higher priority") 6981ec31 ("page_alloc: introduce zone_movable_limit[] to keep movable limit for nodes") 34b71f1e ("page_alloc: add movable_memmap kernel parameter") 4d59a751 ("x86: get pg_data_t's memory from other node") Later we should have patches that will make sure kernel put page table and vmemmap on local node ram instead of push them down to node0. Also need to find way to put other kernel used ram to local node ram.

Use a percpu counter rather than atomic types for shrinker accounting. There's no need for ultimate accuracy in the shrinker, so this should come a little more cheaply. The percpu struct is somewhat large, but there was a big gap before the cache-aligned s_es_lru_lock anyway, and it fits nicely in there.

The kdb_defcmd can only be used to display the available command aliases while using the kernel debug shell. If you try to define a new macro while the kernel debugger is active it will oops. The debug shell macros must use pre-allocated memory set aside at the time kdb_init() is run, and the kdb_defcmd is restricted to only working at the time that the kdb_init sequence is being run, which only occurs if you actually activate the kernel debugger.

Recently some code inspection was done after fixing a problem with kmalloc used while in the kernel debugger context (which is not legal), and it turned up the fact that kdb ll command will oops the kernel. Given that there have been zero bug reports on the command combined with the fact it will oops the kernel it is clearly not being used. Instead of fixing it, it will be removed.

The help command was chopping all the usage instructions such that they were not readable. Example: bta [D|R|S|T|C|Z|E|U|I| Backtrace all processes matching state flag per_cpu <sym> [<bytes>] [<c Display per_cpu variables Where as it should look like: bta [D|R|S|T|C|Z|E|U|I|M|A] Backtrace all processes matching state flag per_cpu <sym> [<bytes>] [<cpu>] Display per_cpu variables All that is needed is to check the how long the cmd_usage is and jump to the next line when appropriate.

Maxime reported that strcpy(s->usage, s->usage+1) has no definitive guarantee that it will work on all archs the same way when you have overlapping memory. The fix is simple for the kdb code because we still have the original string memory in the function scope, so we just have to use that as the argument instead.

Added missing Kconfig option KDB_CONTINUE_CATASTROPHIC which lead to a dead ifdef block in kernel/debug/kdb/kdb_main.c:73-75. The code using KDB_CONTINUE_CATASTROPHIC was originally introduced in commit '5d5314d6' by Jason Wessel. This patchset ("kdb: core for kgdb back end (1 of 2)") added platform independent part of kdb to the linux kernel. The Kernel option however, even though it had the same options and behaviour on all supported architectures, was part of the x86 and ia64 patchset of KDB and therefore not pulled into the mainline kernel tree. I actually took the originally written Kconfig by Keith Owens <kaos@sgi.com> (2003-06-20 according to KDB changelog) and changed it to reflect the correct behaviour, as the KDUMP patchset is not part of the kernel and the expected functionality is missing from it.

We can't look up the address of the entry point of the function simply via that function symbol for all architectures. For PPC64 ABI, actually there is a function descriptors structure. A function descriptor is a three doubleword data structure that contains the following values: * The first doubleword contains the address of the entry point of the function. * The second doubleword contains the TOC base address for the function. * The third doubleword contains the environment pointer for languages such as Pascal and PL/1. So we should call a wapperred dereference_function_descriptor() to get the address of the entry point of the function. Note this is also safe for other architecture after refer to "include/asm-generic/sections.h" since: dereference_function_descriptor(p) always is (p) if without arched definition.

When locally adding in some additional kdb commands, I stumbled across an issue with the dynamic expansion of the kdb command table. When the number of kdb commands exceeds the size of the statically allocated kdb_base_commands[] array, additional space is allocated in the kdb_register_repeat() routine. The unused portion of the newly allocated array was not being initialized to zero properly and this would result in segfaults when help '?' was executed or when a search for a non-existing command would traverse the command table beyond the end of valid command entries and then attempt to use the non-zeroed area as actual command entries.

Add a target that allows a fast device such as an SSD to be used as a cache for a slower device such as a disk. A plug-in architecture was chosen so that the decisions about which data to migrate and when are delegated to interchangeable tunable policy modules. The first general purpose module we have developed, called "mq" (multiqueue), follows in the next patch. Other modules are under development.
