SubjectRe: [GIT PULL] ext4 updates for 4.15
I forgot to mention, there's a merge conflict when pulling the ext4
and fscrypt trees. The fixup is relatively straightforward:

commit daf886f04e60eda3bbc957e79d81d72965afd947
Merge: a0b3bc855374 232530680290
Author: Theodore Ts'o <tytso@mit.edu>
Date: Sun Nov 12 22:03:15 2017 -0500

Merge tag 'ext4_for_linus' into test

Add support for online resizing of file systems with bigalloc. Fix a
two data corruption bugs involving DAX, as well as a corruption bug
after a crash during a racing fallocate and delayed allocation.
Finally, a number of cleanups and optimizations.
