Modified files:
sys/nfsclient nfs_bio.c nfs_node.c nfsnode.h
Log:
Remove the NFS client rslock. The rslock was used to serialize
writers that want to extend the file. It was also used to serialize
readers that might want to read the last block of the file (with a
writer extending the file). Now that we support vnode locking for
NFS, the rslock is unnecessary. Writers grab the exclusive vnode
lock before writing and readers grab the shared (or in some cases
the exclusive) lock.
