/usr/bin/awk spins in user-mode forever, according to strace it doesn't do any syscalls. I didn't even try to investigate.

Jan, I gave up.
Whatever I did xfstests-dev/check reports a lot of failures, kernel bugs, and finally either crashes the kernel or hangs.
With or without this change, and I didn't notice any warning from lockdep. So I hope we can apply this patch. At least 1/2 which fixes a bug.
Oleg.
