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.
