From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx> The following patchset is mainly for improving support for re-exporting NFSv4 as NFSv3. However it also includes one generic bugfix for NFSv3 to allow zero length writes. It also improves the writeback performance by replacing the rwsem with a lock-free errseq_t-based method. Jeff Layton (3): nfsd: Add errno mapping for EREMOTEIO nfsd: Retry once in nfsd_open on an -EOPENSTALE return nfsd: allow lockd to be forcibly disabled Peng Tao (1): nfsd: map EBADF Trond Myklebust (5): nfs: Add export support for weak cache consistency attributes nfsd: NFSv3 should allow zero length writes nfsd: Add a tracepoint for errors in nfsd4_clone_file_range() nfsd: Replace use of rwsem with errseq_t nfsd: Ignore rpcbind errors on nfsd startup fs/nfs/export.c | 24 ++++++++++ fs/nfsd/filecache.c | 1 - fs/nfsd/filecache.h | 1 - fs/nfsd/nfs3xdr.c | 83 ++++++++++++++++++++++----------- fs/nfsd/nfs4proc.c | 18 +++---- fs/nfsd/nfs4xdr.c | 6 +-- fs/nfsd/nfsctl.c | 7 ++- fs/nfsd/nfsd.h | 1 + fs/nfsd/nfsproc.c | 3 ++ fs/nfsd/nfssvc.c | 29 +++++++++++- fs/nfsd/trace.h | 50 ++++++++++++++++++++ fs/nfsd/vfs.c | 85 +++++++++++++++++++++++----------- fs/nfsd/vfs.h | 8 ++-- include/linux/exportfs.h | 3 ++ include/linux/sunrpc/svcsock.h | 5 +- net/sunrpc/svc.c | 2 +- net/sunrpc/svcsock.c | 14 +++--- 17 files changed, 257 insertions(+), 83 deletions(-) -- 2.33.1
