      NFS: Don't run wake_up_bit() when nobody is waiting... · b4f937cf
      Trond Myklebust authored
      "perf lock" shows fairly heavy contention for the bit waitqueue locks
      when doing an I/O heavy workload.
      Use a bit to tell whether or not there has been contention for a lock
      so that we can optimise away the bit waitqueue options in those cases.

      nfs: add export operations · 20fa1902
      Peng Tao authored
      This support for opening files on NFS by file handle, both through the
      open_by_handle syscall, and for re-exporting NFS (for example using a
      different version).  The support is very basic for now, as each open by
      handle will have to do an NFSv4 open operation on the wire.  In the
      future this will hopefully be mitigated by an open file cache, as well
      as various optimizations in NFS for this specific case.
