[Cluster-devel] [PATCH v7 05/13] fat: make fat_update_time get its own timestamp

In later patches, we're going to drop the "now" parameter from the
update_time operation. Fix fat_update_time to fetch its own timestamp.
It turns out that this is easily done by just passing a NULL timestamp
pointer to fat_update_time.

Also, it may be that things have changed by the time we get to calling
fat_update_time after checking inode_needs_update_time. Ensure that we
attempt the i_version bump if any of the S_* flags besides S_ATIME are
set.
