Novfs guys, I haven't looked at the code, but this is a familiar signature. With the newer kernels, you must be absolutely certain that there are no dentries hanging around during umount. It's no longer enough to clear them up in your put_super routine. That's assuming that you're not leaking a dentry elsewhere, of course. :) Here's the fix we used for reiserfs: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdif... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
