fuse: sync fuse_kernel.h from linux 3.11.0(-rc3) header
The linux 3.11 fuse kernel header supports up through version 7.22. Gluster has incrementally supported versions up to 7.22. This is a hard sync of the most recent kernel header to resolve various, minor descrepencies and facilitate updates going forward. The following changes are included: - Re-typed data structure definitions. - Missing comments and init flag definitions (i.e., splice). - Code format and whitespace differences. No functional changes are included. BUG: 990744 Change-Id: I86921ef7be56d31bab332cf8589262c2b9348221 Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-on: http://review.gluster.org/5490 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
