[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
