X-Git-Tag: firefly_0821_release~9833^2~3036^2~1

ocfs2: send SIGXFSZ if new filesize exceeds limit -v2

This patch makes ocfs2 send SIGXFSZ if new file size exceeds the rlimit.
Processes may get SIGXFSZ on one node (in the cluster) while others will
not on another if file size limits are different on the two nodes.
