Modified files:
sys/kern vfs_lookup.c
Log:
- Get rid of PDIRUNLOCK, instead, we fixup the lock state immediately after
calling VOP_LOOKUP(). Rather than having each filesystem check the
LOCKPARENT flag, we simply check it once here and unlock as required.
The only unusual case is ISDOTDOT, where we require an unlocked vnode
on return. Relocking this vnode with the child locked is allowed since
the child is actually its parent.
- Add a few asserts for some unusual conditions that I do not believe can
happen. These will later go away and turn into implementations for these
conditions.
