Server backend storage hang should not cause the mount point to hang.
Submitted-by: Krishna Srinivas <krishna@gluster.com> NOTE: fixed compilation issues in posix.c introduced while merging storage/posix polls for FS/kernel being functional by issuing statvfs() call. In case statvfs expires the timer, storage/posix will send CHILD_DOWN to upper translator. Ultimately this will cause protocol/server to disconnect all clients connected and also cleans up the data structures. Hence if soft lockup or other kernel bug causes backend FS to hang, the clients will not be hung. Signed-off-by: Krishna Srinivas <krishna@gluster.com> Signed-off-by: Anand V.
