Description Mark Fasheh 2005-07-08 02:15:21 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040803

Description of problem:
kjournald is missing a check to JFS_UNMOUNT before it schedules away in it's
main function (kjournald() in fs/jbd/journal.c). If a journal is initialized and
quickly shut down (as may happen during OCFS2 recovery of a node) the call to
journal_destroy() will hang in journal_kill_thread() waiting for kjournald() to
see the JFS_UNMOUNT. A very small patch to fix this can be found at:
http://marc.theaimsgroup.com/?l=ext2-devel&m=112077008603349&w=2

Version-Release number of selected component (if applicable):


How reproducible:
Sometimes

Steps to Reproduce:
1.call journal_init_inode()
2.call journal_load()
3.call journal_destroy()

Patch looks OK to me; it has been proposed upstream and I've ACKed it there too.
