Subject: [PATCH 00/31] Swap over NFS -v20
Newsgroups: gmane.linux.kernel
Date: Thursday 1st October 2009 14:04:18 UTC (over 7 years ago)
Hi,

Here's the latest version of swap over NFS series since -v19 last October
by
Peter Zijlstra. Peter does not have time to pursue this further (though he
has
not lost interest) and that led me to take over this patchset and try
merging
upstream.

The patches are against the current mmotm. It does not support SLQB, yet.
These patches can also be found online here:
	http://www.suse.de/~sjayaraman/patches/swap-over-nfs/

The swap over NFS patches are being shipped with openSUSE 11.1 and SLE 11
(with
CONFIG_NFS_SWAP enabled by default) for several months now. There have been
no bugs reported so far due to these patches and it has been found stable.

Changes since -v19:
 - rebased patches against current -mm
 - adapted changes pertaining to using zone->watermarks array
 - dropped cleanup patches/fixes that have already made to upstream
 - dropped the patch that remove nfs mempools
 - fixed racy nature of sync_page in swap_sync_page (NeilBrown)
 - fixed use of uninitialized variable in cache_grow() (Miklos Szeredi)
 - fixed a bug in bnx2 driver (Jiri Bohac)
 - fixed null-pointer dereferences in swapfile code path when s_bdev is
NULL

Thanks,
Suresh Jayaraman
