Merge tag 'upstream-3.16-rc1-v2' of git://git.infradead.org/linux-ubifs
Pull UBIFS updates from Artem Bityutskiy:
"This contains several UBIFS fixes. One of them fixes a race condition
between the mmap page fault path and fsync. Another just removes a
bogus assertion from the UBIFS memory shrinker.
UBIFS also started honoring the MS_SILENT mount flag, so now it won't
print many I/O errors when user-space just tries to probe for the FS.
Rest of the changes are rather minor UBI/UBIFS fixes, improvements,
and clean-ups"
