Change the second and third args to struct vfsops' (*vfs_mount)() to
...
'const char *', and 'void *', respectively. The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions. The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

NFS performance improvement from Doug Rabson/FreeBSD:
...
Improve the queuing algorithms used by NFS' asynchronous i/o. The
existing mechanism uses a global queue for some buffers and the
vp->b_dirtyblkhd queue for others. This turns sequential writes into
randomly ordered writes to the server, affecting both read and write
performance. The existing mechanism also copes badly with hung
servers, tending to block accesses to other servers when all the iods
are waiting for a hung server.
The new mechanism uses a queue for each mount point. All asynchronous
i/o goes through this queue which preserves the ordering of requests.
A simple mechanism ensures that the iods are shared out fairly between
active mount points.

Start XIDs at a value based on the current time, not 0. This avoids nasty

XID confusions with servers that cache them over a long period and

Problems: because of the sanity check that is done by comparing the system
time with filesystem time, XIDs will start at 0 until root is mounted,
which means it isn't completely safe for diskless setups. But it's clearly
better than it was. It would also be cleaner if all XID handling (more
generally, all RPC handling) within the kernel went through the
same functions.

Add cookie support. Stash cookies in the word prior to the end of
...
each entry, and read them out in nfs_readdir().
Caveat: our current caching method for directory blocks uses the
server offset of the first directory entry as an identifier, so a
Linux emulation getdirentries() will wind up retrieving one block from
the NFS server for each directory entry, unnecessarily thrashing the
cache. The situation isn't as bad for other emulations.
Instead of getblk(), we need to write a routine to scan each cache
block associated with vp to find a cookie that matches at some
directory entry. Some later time.

blow away all vestiges of nfsnode locking.
...
(1) it's unnecessary
(2) it causes machines to hang (yup!)
(3) it'd be gone in a few days anyway (it'd been yanked out
of 4.4-Lite by macklem long ago)
It was only there because macklem couldn't originally decide if things
should be locked, or not...
