Nice to know - why didn't anyone email me or report this to the
list when the bug was first found? I mean, I wrote that code, I know
what it is supposed to be doing and as a result should be able
help find and fix the bug. Can you please post what details you have
about the problem (test case, stack traces, debugging info, etc)
so I can try to find the problem.
This is a regression that is in the mainline kernel that is due to
be released probably in the next couple of days. Having a little
bit of time to try and find the bug would have been nice...
