  This patchset resends some patches that related to FUSE consistency
improvements in the mailing list.

The 1st patch fixes a staleness-checking issue, which is the v2 version
of the patch[1].

The 2nd patch is a resend version of the patch[2] with its commit message
rewritten.

The 3rd and 4th patches are new versions of the patch[3] and the patch[4],
FUSE filesystems are able to implement the close-to-open (CTO) consistency
semantics with the help of these two patches. The 5th patch is a new
patch which improves the explanation of FUSE cache mode and consistency
models in the documentation.

Yeah our internal production environment will also benefit from this
cache consistency enhancement.  It would be great if this feature could
be improved and finally gets merged.
