Modified files:
sys/kern vfs_lookup.c
Log:
- Consistently track ni_dvp and ni_vp with dvfslocked and vfslocked rather
than trying to optimize it into a single lock. This adds more calls to
lock giant with non smpsafe filesystems but is the only way to reliably
hold the correct lock.
- Remove an invalid assert in the mountedhere case in lookup and fix the
code to properly deal with the scenario. We can actually have a lookup
that returns dp == dvp with mountedhere set with certain unmount races.
