Re: 2.6.12.2 dies after 24 hours

Sorry for the confusion, you're hitting the other mmap_sem -> transaction lock
problem. This one should be solvable with an iget so we make sure not to do
the final unlink until after the mmap sem is dropped.

Lets see what I can do...

Oh dang.

I thought this last crash after upgrading to 2.6.12.2 was due to the IRQ BALANCE issue Lars suggested, but you're saying that it's actually a whole different bug, though similar to the previous "prepare_write ... copy_from_user ... commit_write" lock problem?

Is this something new between 2.6.4-mm2 and 2.6.12.2? Or would it have always been present, just for some reason we're hitting it in 2.6.12 now but weren't hitting it in 2.6.4?

I feel we're moving backwards... :(
