Subject: [2.6.21] BUG: at fs/inotify.c:172 set_dentry_child_flags()

Got this BUG_ON twice in a row, just found it by scrolling thru my
dmesg.

=======================

this was probably triggered by this small shell script i have:

while true;
do
	ls -1 \$MAIL/new/ | wc -l;
	inotifywait -e CREATE -e DELETE -e MOVE \$MAIL/new/ > /dev/null 2>/dev/null || break;
done

$MAIL is mounted from a reiserfs filesystem.
