sys/nfs4client nfs4_vnops.c
sys/fs/smbfs smbfs_vnops.c
Log:
- We no longer have to bother with PDIRUNLOCK, lookup() handles it for us.
- Network filesystems are written with a special idiom that checks the
cache first, and may even unlock dvp before discovering that a network
round-trip is required to resolve the name. I believe dvp is prevented
from being recycled even in the forced unmount case by the shared lock
on the mount point. If not, this code should grow checks for VI_DOOMED
after it relocks dvp or it will access NULL v_data fields.
