Modified files:
sys/kern vfs_lookup.c
Log:
- Set cn_lkflags to LK_SHARED in the LOOKUP_SHARED case so that we only
acquire shared locks on intermediate directories.
- For the LASTCN, we may have to LK_UPGRADE the parent directory before
we lookup the last component.
- Acquire VFS_ROOT and dp locks based on the cn_lkflag.
