Btrfs Changes Rejected For The Linux 3.17 Kernel

[LLStarks]

Poor Butters.

He'll never be ready to replace ext4.

[0xBADCODE]

Reduced patchset has made it to 3.17 before -rc1,

Somewhat compacted version of this patch set (i.e. fixes of nasty issues rather than less significant stuff) has actually made it into 3.17-rc1.

Just looking into GIT commits log:

    Merge branch 'for-linus2' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
    
    Pull btrfs updates from Chris Mason:
     "These are all fixes I'd like to get out to a broader audience.
    
      The biggest of the bunch is Mark's quota fix, which is also in the
      SUSE kernel, and makes our subvolume quotas dramatically more
      accurate.
    
      I've been running xfstests with these against your current git
      overnight, but I'm queueing up longer tests as well"
    
    * 'for-linus2' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:
      btrfs: disable strict file flushes for renames and truncates
      Btrfs: fix csum tree corruption, duplicate and outdated checksums
      Btrfs: Fix memory corruption by ulist_add_merge() on 32bit arch
      Btrfs: fix compressed write corruption on enospc
      btrfs: correctly handle return from ulist_add
      btrfs: qgroup: account shared subtrees during snapshot delete
      Btrfs: read lock extent buffer while walking backrefs
      Btrfs: __btrfs_mod_ref should always use no_quota
      btrfs: adjust statfs calculations according to raid profiles

And speaking of butter replacing ext4... in fact I use btrfs on some non-critical systems and it "just works" for simple cases. Yet it provides nice things like snapshots and recent versions got fairly good performance as well, at least in more or less common use cases.
