Last modified: 2009-07-06 17:28:54 EDT
Description of problem: A bug in inotify_user.c Following comment is at fs/inotify_user.c:287 /* coalescing: drop this event if it is a dupe of the previous */ I think the previous event in the comment should be the last event in the link list. But inotify_dev_get_event return the first event in the list. In addition, it doesn't check whether the list is empty http://kerneltrap.org/mailarchive/git-commits-head/2008/2/6/748474 Version-Release number of selected component (if applicable): 2.6.18-92.el5 How reproducible: Always Steps to Reproduce: 1.

Alright, I suck. This was intended for -100.el5 but the bz flags blocked me and my scripts failed to reflect this. :( Moving back to POST to show it is still on my queue.
