Experimental NFS client patches for Linux 2.4.17

Please note: the patches in this directory represent what I am currently using on my machine. They are experimental, and are made available only so that people can test out features that I plan for inclusion in the kernel in the future.

A brief explanation of the patches in this directory

linux-2.4.17-seekdir.dif:

An experimental patch for fixing a problem that is due to NFSv(2|3) readdir returning (32|64) bit unsigned offsets.

If you are seeing problems involving files that mysteriously disappear from your directory listings, then please consider applying this patch.

NOTE: You might still have to set the '32bitclients' export option on some IRIX servers due to a remaining bug in glibc-2.2.

linux-2.4.17-fattr.dif:

A patch to fix a race when we receive updated file attribute information from the server.

linux-2.4.17-pathconf.dif:

A patch that ensures we don't exceed the maximum file name length on an NFSv3 partition.

linux-2.4.17-cto.dif:

A very experimental patch --initially by Chuck Lever, but now heavily changed by me-- which improves the NFS clients ability to cache lookups. This can make quite a difference to the performance of "make" and other such utilities.

linux-2.4.17-rdplus.dif:

Implements the NFSv3 READDIRPLUS function that allows further file lookup caching improvements

This patch assumes you have already applied the preceeding close-to-open fixes in linux-2.4.17-cto.dif and the patch linux-2.4.17-fattr.dif

linux-2.4.17-ping.dif:

The RPC ping code for improving stability on UDP.

linux-2.4.17-rpc_bkl.dif:

A patch that removes the need for the Big Kernel Lock within the RPC code.

This patch assumes you have already applied linux-2.4.17-fattr.dif

linux-2.4.17-svc_tcp.dif:

A patch implementing NFS-over-TCP for the knfsd server, which was written by Shirish Kalele.

linux-2.4.17-rpc_tweaks.dif:

A patch of further tweaks to be applied on top of the NFS-over-TCP knfsd server. Amongst other things, it enables 32k read/writes for Linux.

linux-2.4.17-odirect.dif:

A patch by Chuck Lever that implements experimental support for direct I/O over NFS. See the Configure.help file for further info.

Note: you should really consider applying linux-2.4.17-pathconf.dif together with this patch. This will allow you to align your O_DIRECT writes on the server's hardware block boundaries rather than being forced to align on the NFS client block boundaries.

linux-2.4.17-NFS_ALL.dif:

A patch containing all of the above.
