cifs: Fix caching to try to do open O_WRONLY as rdwr on server
[ Upstream commit e9e62243a3e2322cf639f653a0b0a88a76446ce7 ]
When we're engaged in local caching of a cifs filesystem, we cannot perform
caching of a partially written cache granule unless we can read the rest of
the granule. This can result in unexpected access errors being reported to
the user.
Fix this by the following: if a file is opened O_WRONLY locally, but the
mount was given the "-o fsc" flag, try first opening the remote file with
GENERIC_READ|GENERIC_WRITE and if that returns -EACCES, try dropping the
GENERIC_READ and doing the open again. If that last succeeds, invalidate
the cache for that file as for O_DIRECT.

smb: convert to ctime accessor functions
In later patches, we're going to change how the inode's ctime field is
used. Switch to using accessor functions instead of raw accesses of
inode->i_ctime.
