These are\n  already shipping in the sles kernel, and they give btrfs the ability\n  to abort transactions and go readonly on errors.  It involves a lot of\n  churn as they clarify BUG_ONs, and remove the ones we now properly\n  deal with.\n\n  Josef reworked the way our metadata interacts with the page cache.\n  page-\u003eprivate now points to the btrfs extent_buffer object, which\n  makes everything faster.  He changed it so we write an whole extent\n  buffer at a time instead of allowing individual pages to go down,,\n  which will be important for the raid5/6 code (for the 3.5 merge\n  window ;)\n\n  Josef also made us more aggressive about dropping pages for metadata\n  blocks that were freed due to COW.  Overall, our metadata caching is\n  much faster now.\n\n  We\u0027ve integrated my patch for metadata bigger than the page size.\n  This allows metadata blocks up to 64KB in size.  In practice 16K and\n  32K seem to work best.  For workloads with lots of metadata, this cuts\n  down the size of the extent allocation tree dramatically and fragments\n  much less.\n\n  Scrub was updated to support the larger block sizes, which ended up\n  being a fairly large change (thanks Stefan Behrens).\n\n  We also have an assortment of fixes and updates, especially to the\n  balancing code (Ilya Dryomov), the back ref walker (Jan Schmidt) and\n  the defragging code (Liu Bo).\"\n\nFixed up trivial conflicts in fs/btrfs/scrub.c that were just due to\nremoval of the second argument to k[un]map_atomic() in commit\n7ac687d9e047.\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (75 commits)\n  Btrfs: update the checks for mixed block groups with big metadata blocks\n  Btrfs: update to the right index of defragment\n  Btrfs: do not bother to defrag an extent if it is a big real extent\n  Btrfs: add a check to decide if we should defrag the range\n  Btrfs: fix recursive defragment with autodefrag option\n  Btrfs: fix the mismatch of page-\u003emapping\n  Btrfs: fix race between direct io and autodefrag\n  Btrfs: fix deadlock during allocating chunks\n  Btrfs: show useful info in space reservation tracepoint\n  Btrfs: don\u0027t use crc items bigger than 4KB\n  Btrfs: flush out and clean up any block device pages during mount\n  btrfs: disallow unequal data/metadata blocksize for mixed block groups\n  Btrfs: enhance superblock sanity checks\n  Btrfs: change scrub to support big blocks\n  Btrfs: minor cleanup in scrub\n  Btrfs: introduce common define for max number of mirrors\n  Btrfs: fix infinite loop in btrfs_shrink_device()\n  Btrfs: fix memory leak in resolver code\n  Btrfs: allow dup for data chunks in mixed mode\n  Btrfs: validate target profiles only if we are going to use them\n  ...\n"

Furthermore, although theoretically it could trigger under\n  normal direct I/O writes, it only seems to trigger if you are issuing\n  a huge number of AIO writes, such that a just-written page can get\n  evicted from memory, and then read back into memory, before the\n  workqueue has a chance to update the extent tree.\n\n  This race has been around for a little over a year, and no one noticed\n  until two months ago; it only happens under fairly exotic conditions,\n  and in fact even after trying very hard to create a simple repro under\n  lab conditions, we could only reproduce the problem and confirm the\n  fix on production servers running MySQL on very fast PCIe-attached\n  flash devices.\n\n  Given that Dave was able to hit this problem pretty quickly, if we\n  confirm that this commit is at fault, the only reasonable thing to do\n  is to revert it IMO.\"\n\nReported-and-tested-by: Dave Jones \u003cdavej@redhat.com\u003e\nAcked-by: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

With that done I think we\u0027ll finally\nturn off the \"EXPERIMENTAL\" dependency for v4 (though that\u0027s mostly\nsymbolic as it\u0027s been on by default in distro\u0027s for a while).\n\nAnd the list of 4.1 todo\u0027s should be achievable for 3.5 as well:\n\n   http://wiki.linux-nfs.org/wiki/index.php/Server_4.0_and_4.1_issues\n\nthough we may still want a bit more experience with it before turning it\non by default.\n\n* \u0027for-3.4\u0027 of git://linux-nfs.org/~bfields/linux: (55 commits)\n  nfsd: only register cld pipe notifier when CONFIG_NFSD_V4 is enabled\n  nfsd4: use auth_unix unconditionally on backchannel\n  nfsd: fix NULL pointer dereference in cld_pipe_downcall\n  nfsd4: memory corruption in numeric_name_to_id()\n  sunrpc: skip portmap calls on sessions backchannel\n  nfsd4: allow numeric idmapping\n  nfsd: don\u0027t allow legacy client tracker init for anything but init_net\n  nfsd: add notifier to handle mount/unmount of rpc_pipefs sb\n  nfsd: add the infrastructure to handle the cld upcall\n  nfsd: add a header describing upcall to nfsdcld\n  nfsd: add a per-net-namespace struct for nfsd\n  sunrpc: create nfsd dir in rpc_pipefs\n  nfsd: add nfsd4_client_tracking_ops struct and a way to set it\n  nfsd: convert nfs4_client-\u003ecl_cb_flags to a generic flags field\n  NFSD: Fix nfs4_verifier memory alignment\n  NFSD: Fix warnings when NFSD_DEBUG is not defined\n  nfsd: vfs_llseek() with 32 or 64 bit offsets (hashes)\n  nfsd: rename \u0027int access\u0027 to \u0027int may_flags\u0027 in nfsd_open()\n  ext4: return 32/64-bit dir name hash according to usage type\n  fs: add new FMODE flags: FMODE_32bithash and FMODE_64bithash\n  ...\n"

It holds a number of\n  low level bits with no/few dependencies that are commonly used (eg.\n  memory barriers) and a number of bits with more dependencies that\n  aren\u0027t used in many places (eg.  switch_to()).\n\n  These patches break asm/system.h up into the following core pieces:\n\n    (1) asm/barrier.h\n\n        Move memory barriers here.  This already done for MIPS and Alpha.\n\n    (2) asm/switch_to.h\n\n        Move switch_to() and related stuff here.\n\n    (3) asm/exec.h\n\n        Move arch_align_stack() here.  Other process execution related bits\n        could perhaps go here from asm/processor.h.\n\n    (4) asm/cmpxchg.h\n\n        Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n        frequently used by atomic_xchg() and atomic_cmpxchg().\n\n    (5) asm/bug.h\n\n        Move die() and related bits.\n\n    (6) asm/auxvec.h\n\n        Move AT_VECTOR_SIZE_ARCH here.\n\n  Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.  We\u0027ll find out anything that got broken and fix it..\n\n* tag \u0027split-asm_system_h-for-linus-20120328\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits)\n  Delete all instances of asm/system.h\n  Remove all #inclusions of asm/system.h\n  Add #includes needed to permit the removal of asm/system.h\n  Move all declarations of free_initmem() to linux/mm.h\n  Disintegrate asm/system.h for OpenRISC\n  Split arch_align_stack() out from asm-generic/system.h\n  Split the switch_to() wrapper out of asm-generic/system.h\n  Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h\n  Create asm-generic/barrier.h\n  Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h\n  Disintegrate asm/system.h for Xtensa\n  Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt]\n  Disintegrate asm/system.h for Tile\n  Disintegrate asm/system.h for Sparc\n  Disintegrate asm/system.h for SH\n  Disintegrate asm/system.h for Score\n  Disintegrate asm/system.h for S390\n  Disintegrate asm/system.h for PowerPC\n  Disintegrate asm/system.h for PA-RISC\n  Disintegrate asm/system.h for MN10300\n  ...\n"

It treats them as a filesystem block address, rather than\na disk address. This is wrong because the range passed in is a\nlinear representation, while the filesystem block address notation\nis a sparse representation. Hence we cannot convert the range direct\nto filesystem block units and then use that for calculating the\nrange to trim.\n\nWhile this sounds dangerous, the problem is limited to calculating\nwhat AGs need to be trimmed. The code that calcuates the actual\nranges to trim gets the right result (i.e. only ever discards free\nspace), even though it uses the wrong ranges to limit what is\ntrimmed. Hence this is not a bug that endangers user data.\n\nFix this by treating the range as a disk address range and use the\nappropriate functions to convert the range into the desired formats\nfor calculations.\n\nFurther, fix the first free extent lookup (the longest) to actually\nfind the largest free extent. Currently this lookup uses a \u003c\u003d\nlookup, which results in finding the extent to the left of the\nlargest because we can never get an exact match on the largest\nextent. This is due to the fact that while we know it\u0027s size, we\ndon\u0027t know it\u0027s location and so the exact match fails and we move\none record to the left to get the next largest extent. Instead, use\na \u003e\u003d search so that the lookup returns the largest extent regardless\nof the fact we don\u0027t get an exact match on it.\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Ben Myers \u003cbpm@sgi.com\u003e\n"

So\ninstead make it so that if we see an io error in endio we just mark the eb as\nhaving an IO error and then in btree_read_extent_buffer_pages we will manually\ntry other mirrors and then overwrite the bad mirror if we find a good copy.\nThis works with larger than page size blocks.
