      lockd: add code to handle deferred lock requests · 1a8322b2
      Marc Eshel authored 
      
Rewrite nlmsvc_lock() to use the asynchronous interface.

As with testlock, we answer nlm requests in nlmsvc_lock by first looking up
the block and then using the results we find in the block if B_QUEUED is
set, and calling vfs_lock_file() otherwise.

If this a new lock request and we get -EINPROGRESS return on a non-blocking
request then we defer the request.

Also modify nlmsvc_unlock() to call the filesystem method if appropriate.

      [PATCH] knfsd: Allow lockd to drop replies as appropriate · d343fce1
      NeilBrown authored 
      
It is possible for the ->fopen callback from lockd into nfsd to find that an
answer cannot be given straight away (an upcall is needed) and so the request
has to be 'dropped', to be retried later.  That error status is not currently
propagated back.

So:
  Change nlm_fopen to return nlm error codes (rather than a private
  protocol) and define a new nlm_drop_reply code.
  Cause nlm_drop_reply to cause the rpc request to get rpc_drop_reply
  when this error comes back.
  Cause svc_process to drop a request which returns a status of
  rpc_drop_reply.

      [PATCH] knfsd: Fix bug in recent lockd patches that can cause reclaim to fail · 4481d103
      NeilBrown authored 
      
When an nfs server shuts down, lockd needs to release all the locks even
though the client still holds them.

It should therefore not 'unmonitor' the clients, so that the files in nfs/sm
will still be there when the nfs server restarts, so that those clients will
be told to reclaim their locks.

However the hosts are fully unmonitored, so statd may well remove the files.

lockd has a test for 'sm_sticky' and avoid the unmonitor call if it is set,
but it is currently not set.

So set it when tearing down lockd.

Semaphore to mutex conversion.

The conversion was generated via scripts, and the result was validated
automatically via a script as well.

      lockd: Remove FL_LOCKD flag · 7117bf3d
      J. Bruce Fields authored 
      
Currently lockd identifies its own locks using the FL_LOCKD flag.  This
doesn't scale well to multiple lock managers--if we did this in nfsv4 too,
for example, we'd be left with only one free flag bit.

Instead, we just check whether the file manager ops (fl_lmops) set on this
lock are our own.

The only use for this is in nlm_traverse_locks, which uses it to find locks
that need cleaning up when freeing a host or a file.

In the long run it might be nice to do reference counting instead of
traversing all the locks like this....

      Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
