Would you like me to resend thee two? Or resend the series? Or are you happy to just if it up? Thanks, NeilBrown
swap-over-NFS currently doesn't work. Even after these patches it still won't work. Some core MM changes are needed. However these patches make a number of improvements to NFS and SUNRPC so that swap-over-NFS can work once those mm changes land. There is one change since the last posting of these patches. The last patch was added to fix a potential hang when enabling swap. Trond/Anna - is their any chance these can go in on the next merge window? Thanks, NeilBrown --- NeilBrown (11): NFS: remove IS_SWAPFILE hack SUNRPC/call_alloc: async tasks mustn't block waiting for memory SUNRPC/auth: async tasks mustn't block waiting for memory SUNRPC/xprt: async tasks mustn't block waiting for memory SUNRPC: remove scheduling boost for "SWAPPER" tasks. NFS: discard NFS_RPC_SWAPFLAGS and RPC_TASK_ROOTCREDS SUNRPC: improve 'swap' handling: scheduling and PF_MEMALLOC NFSv4: keep state manager thread active if swap is enabled NFS: swap IO handling is slightly different for O_DIRECT IO NFS: swap-out must always use STABLE writes. SUNRPC: change locking for xs_swap_enable/disable fs/nfs/direct.c | 48 ++++++++++++++++++++++----------- fs/nfs/file.c | 19 +++++++++---- fs/nfs/nfs4_fs.h | 1 + fs/nfs/nfs4proc.c | 20 ++++++++++++++ fs/nfs/nfs4state.c | 39 ++++++++++++++++++++++----- fs/nfs/read.c | 4 --- fs/nfs/write.c | 2 ++ include/linux/nfs_fs.h | 13 +++------ include/linux/nfs_xdr.h | 2 ++ include/linux/sunrpc/auth.h | 1 + include/linux/sunrpc/sched.h | 1 - include/trace/events/sunrpc.h | 1 - net/sunrpc/auth.c | 8 ++++-- net/sunrpc/auth_gss/auth_gss.c | 6 ++++- net/sunrpc/auth_unix.c | 10 +++++-- net/sunrpc/clnt.c | 7 +++-- net/sunrpc/sched.c | 29 +++++++++++++------- net/sunrpc/xprt.c | 19 +++++-------- net/sunrpc/xprtrdma/transport.c | 10 ++++--- net/sunrpc/xprtsock.c | 34 ++++++++++++----------- 20 files changed, 185 insertions(+), 89 deletions(-) -- Signature
