Modified files:
sys/nfsclient nfs.h nfs_lock.c nfs_lock.h nfs_nfsiod.c
nfs_subs.c
Log:
For reasons unknown, the nfs locking code used a fifo to send requests to
userland and a dedicated system call to get replies.
The vnode-bypass of fifos broke this into a panic.
Ditch all the magic and create a device /dev/nfslock instead, and
use that for both directions apart from the shorter path, this is
also faster because the device driver runs Giant free using the
vnode bypass.
