src/usr.sbin/puffs/mount_9p: ninepuffs.c
Log Message:
mount_9p: don't cache path names by default
Caching path names doesn't handle file changes by host, which is
not expected for normal usages. So turn it off by default.
Instead, -C option is added to turn it on.
Patch from k-goda@IIJ with my tweaks
