Modified files:
sys/sys filedesc.h
Log:
Split the FILEDESC_LOCK in two variants.
FILEDESC_LOCK_FAST will just grab the interlocking mutex and hold
it. This should be used for simple modifications of a field.
FILEDESC_LOCK holds a (homegrown) sleepable lock which should be used
where sleeping is required.
The homegrown lock will probably be replaced with a generic type of lock
once we have found out how that should look.
