Subject: [GIT PULL] ext4 updates for 4.11

Hi Linus,

Please merge the fscrypt tree first, or the diff stats that you see
will include some additional fscrypt changes (I had to merge in a
portion of the fscrypt branch for dependency reasons).

The following changes since commit 56735be05353b085a0862ca4c4943628df3420ca:

  Merge branch 'fscrypt' into d (2017-01-08 20:57:35 -0500)

  ext4: rename EXT4_IOC_GOINGDOWN to EXT4_IOC_SHUTDOWN (2017-02-20 15:34:59 -0500)

For this cycle we add support for the shutdown ioctl, which is
primarily used for testing, but which can be useful on production
systems when a scratch volume is being destroyed and the data on it
doesn't need to be saved.  This found (and we fixed) a number of bugs
with ext4's recovery to corrupted file system --- the bugs increased
the amount of data that could be potentially lost, and in the case of
the inline data feature, could cause the kernel to BUG.

Also included are a number of other bug fixes, including in ext4's
fscrypt, DAX, inline data support.

Christoph Hellwig (2):
      ext4: fix DAX write locking
      dax: assert that i_rwsem is held exclusive for writes

Eric Biggers (1):
      ext4: fix use-after-iput when fscrypt contexts are inconsistent

Jan Kara (4):
      ext4: trim allocation requests to group size
      ext4: fix data corruption in data=journal mode
      ext4: fix stripe-unaligned allocations
      ext4: do not use stripe_width if it is not set

Jason A. Donenfeld (1):
      ext4: move halfmd4 into hash.c directly

Roman Pen (2):
      ext4: Include forgotten start block on fallocate insert range
      ext4: do not polute the extents cache while shifting extents

Sahitya Tummala (1):
      jbd2: fix use after free in kjournald2()

Theodore Ts'o (15):
      ext4: add debug_want_extra_isize mount option
      ext4: fix deadlock between inline_data and ext4_expand_extra_isize_ea()
      ext4: avoid calling ext4_mark_inode_dirty() under unneeded semaphores
      ext4: propagate error values from ext4_inline_data_truncate()
      ext4: replace BUG_ON with WARN_ON in mb_find_extent()
      ext4: fix inline data error paths
      jbd2: don't leak modified metadata buffers on an aborted journal
      ext4: preserve the needs_recovery flag when the journal is aborted
      ext4: return EROFS if device is r/o and journal replay is needed
      ext4: rename s_resize_flags to s_ext4_flags
      ext4: add shutdown bit and check for it
      ext4: add EXT4_IOC_GOINGDOWN ioctl
      ext4: don't BUG when truncating encrypted inodes on the orphan list
      ext4: fix fencepost in s_first_meta_bg validation
      ext4: rename EXT4_IOC_GOINGDOWN to EXT4_IOC_SHUTDOWN
