Subject: [PATCH 0/5] FUSE consistency improvements

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.
