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... :(
