Date: Thu, 1 Oct 2009 19:34:18 +0530 From: Suresh Jayaraman <sjayaraman@...e.de> To: Linus Torvalds <torvalds@...ux-foundation.org>, Andrew Morton <akpm@...ux-foundation.org>, linux-kernel@...r.kernel.org, linux-mm@...ck.org Cc: netdev@...r.kernel.org, Neil Brown <neilb@...e.de>, Miklos Szeredi <mszeredi@...e.cz>, Wouter Verhelst <w@...r.be>, Peter Zijlstra <a.p.zijlstra@...llo.nl>, trond.myklebust@....uio.no Subject: [PATCH 00/31] Swap over NFS -v20 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 -- Peter Zijlstra (26) mm: serialize access to min_free_kbytes mm: expose gfp_to_alloc_flags() mm: tag reseve pages mm: sl[au]b: add knowledge of reserve pages mm: kmem_alloc_estimate() mm: allow PF_MEMALLOC from softirq context mm: emergency pool mm: system wide ALLOC_NO_WATERMARK mm: __GFP_MEMALLOC mm: memory reserve management mm: add support for non block device backed swap files mm: methods for teaching filesystems about PG_swapcache pages net: packet split receive api net: sk_allocation() - concentrate socket related allocations selinux: tag avc cache alloc as non-critical netvm: network reserve infrastructure netvm: INET reserves netvm: hook skb allocation to reserves netvm: filter emergency skbs netvm: prevent a stream specific deadlock netvm: skb processing netfilter: NF_QUEUE vs emergency skbs nfs: teach the NFS client how to treat PG_swapcache pages nfs: disable data cache revalidation for swapfiles nfs: enable swap on NFS nfs: fix various memory recursions possible with swap over NFS Jeff Mahoney (1) Fix initialization of ipv4_route_lock Neil Brown (2) swap over network documentation Cope with racy nature of sync_page in swap_sync_page Miklos Szeredi (1) Fix use of uninitialized variable in cache_grow() Suresh Jayaraman (1) swapfile: avoid NULL pointer dereference in swapon when s_bdev is NULL fs/nfs/file.c | 18 fs/nfs/pagelist.c | 2 fs/nfs/write.c | 99 ++++ include/linux/mm_types.h | 1 include/linux/skbuff.h | 28 + include/linux/slab.h | 19 include/net/sock.h | 55 ++ mm/page_alloc.c | 120 ++++-- mm/page_io.c | 2 mm/slab.c | 80 +++- mm/slob.c | 67 +++ mm/slub.c | 89 ++++ mm/swapfile.c | 53 ++ Documentation/filesystems/Locking | 22 + Documentation/filesystems/vfs.txt | 18 Documentation/network-swap.txt | 270 +++++++++++++ drivers/net/bnx2.c | 9 drivers/net/e1000e/netdev.c | 7 drivers/net/igb/igb_main.c | 9 drivers/net/ixgbe/ixgbe_main.c | 14 drivers/net/sky2.c | 16 fs/nfs/Kconfig | 10 fs/nfs/file.c | 6 fs/nfs/inode.c | 6 fs/nfs/internal.h | 7 fs/nfs/pagelist.c | 6 fs/nfs/read.c | 6 fs/nfs/write.c | 53 +- include/linux/buffer_head.h | 1 include/linux/fs.h | 9 include/linux/gfp.h | 3 include/linux/mm.h | 25 + include/linux/mm_types.h | 1 include/linux/mmzone.h | 3 include/linux/nfs_fs.h | 2 include/linux/pagemap.h | 5 include/linux/reserve.h | 198 +++++++++ include/linux/sched.h | 7 include/linux/skbuff.h | 3 include/linux/slab.h | 4 include/linux/slub_def.h | 1 include/linux/sunrpc/xprt.h | 5 include/linux/swap.h | 4 include/net/inet_frag.h | 7 include/net/netns/ipv6.h | 4 include/net/sock.h | 5 kernel/softirq.c | 3 mm/Makefile | 2 mm/internal.h | 15 mm/page_alloc.c | 16 mm/page_io.c | 51 ++ mm/reserve.c | 637 ++++++++++++++++++++++++++++++++ mm/slab.c | 61 ++- mm/slob.c | 16 mm/slub.c | 43 +- mm/swap_state.c | 4 mm/swapfile.c | 30 + mm/vmstat.c | 6 net/Kconfig | 3 net/core/dev.c | 57 ++ net/core/filter.c | 3 net/core/skbuff.c | 137 +++++- net/core/sock.c | 107 +++++ net/ipv4/inet_fragment.c | 3 net/ipv4/ip_fragment.c | 86 ++++ net/ipv4/route.c | 70 +++ net/ipv4/tcp.c | 3 net/ipv4/tcp_input.c | 12 net/ipv4/tcp_output.c | 12 net/ipv6/reassembly.c | 85 ++++ net/ipv6/route.c | 77 +++ net/ipv6/tcp_ipv6.c | 15 net/netfilter/core.c | 3 net/sctp/ulpevent.c | 2 net/sunrpc/Kconfig | 5 net/sunrpc/sched.c | 9 net/sunrpc/xprtsock.c | 68 +++ security/selinux/avc.c | 2 net/core/sock.c | 18 net/ipv4/route.c | 2 80 files changed, 2797 insertions(+), 245 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
