[Ocfs2-devel] [PATCH] ocfs2: send SIGXFSZ if new filesize exceeds limit -v2

[Wengang Wang]

This patch makes ocfs2 send SIGXFSZ if new file size exceeds limit and abort the
operation.
No suprise that processes get SIGXFSZ on one node(in the cluster) while they
don't on another if file size limits are different on the two nodes.
