gluster: add fallocate fop support
Implement support for the fallocate file operation. fallocate allocates blocks for a particular inode such that future writes to the associated region of the file are guaranteed not to fail with ENOSPC. This patch adds fallocate support to the following areas: - libglusterfs - mount/fuse - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi BUG: 949242 Change-Id: Ice8e61351f9d6115c5df68768bc844abbf0ce8bd Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-on: http://review.gluster.org/4969 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
