Subjectcall_usermodehelper() returns -513 when ocfs2 umounting filesystems
Hi, 
We have encountered an error when umounting ocfs2 filesystems.
Function ocfs2_leave_group() calls call_usermodehelper() to stop
heartbeat thread, but it returns -513(ERESTARTNOINTR) in one test.
And after that error, every times umounting the filesystem, it
returns the same error.
And at the same time, there's another kworker thread which is
sending messages to other nodes always return return errno
-512(ERESTARTSYS). So I think these two threads may have
pending signals remain.
This error can not reproduced any longer. Has any ideas?

The log is as follows:
[58463.684504] (kworker/u:1,17332,0):o2net_send_tcp_msg:1332 ERROR: sendmsg returned -512 instead of 104
[58915.213299] ocfs2: Error -513 running user helper "/usr/sbin/ocfs2_hb_ctl -K -u A5FD0ED8733D4F9C98D23B326AD7DE10"
[59406.443615] ocfs2: Error -513 running user helper "/usr/sbin/ocfs2_hb_ctl -K -u A5FD0ED8733D4F9C98D23B326AD7DE10"

Thanks.
