[GIT PULL] ext4 updates for 4.11

[Theodore Ts'o]

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).

Thanks!!

  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.
