fstab was there just fine after -u.
Oh, that still hasn't been fixed?
Looked like it =)
Hm, it was proposed upstream a while ago:
http://lkml.org/lkml/2006/9/27/137
I guess it got lost?
Seems like it. Andrew, did this ever get queued for merge?
Seems not. I think people were hoping that various nasties in there
would go away. We return to userspace with a kernel lock held??
Is a semaphore any worse than the current mutex in this respect? At
least unlocking from another thread doesn't violate semaphore rules. :)
I assume that if we weren't returning to userspace with a lock held, this
mutex problem would simply go away.
Well nobody's asserting that the filesystem must always be locked &
unlocked by the same thread, are they? That'd be a strange rule to
enforce upon the userspace doing the filesystem management wouldn't it?
Or am I thinking about this wrong...
