Check return value in the Gluster driver for fcntl, as pointed
05bba0
out by coverity.
05bba0
05bba0
Cleanup of s->fds is done inline in the error handling for the fcntl()
05bba0
call, rather than in the function cleanup, to keep changes minimal for
05bba0
future backports.
05bba0
05bba0
Downstream-only, as upstream Gluster driver does not use fcntl anymore.
