cec77ff4bf NULL releasedfl after calling deallocate_file_lock() which frees it
to avoid a use-after-free error in the debuglog() call at the top
of the loop.

96f8e17c48 Add a function that checks for duplicate requests (based
on some fairly tight criteria) so we avoid having broken
clients spam rpc.lockd to death.

3d81d1ad2e After talking to Colin,
apply the patch of bin/61718 (which should include/elimatate kern/61122 also).
It seems to fix a few annoying bugs.

aba638209b The callrpc call to unmonitor hosts was passing the wrong xdr
decode/encode functions for the arguments to the statd unmonitor
call.  Fix it.

86eb7cbada Avoid registering for a lock on the server in the event the NFS client
has requested the lock in a non-blocking form, instead returning an
immediate failure.  This appears to help reduce one of my "locks get
lost" symptoms involving lockf(1), which attempts a non-blocking lock
attempt before actually blocking on the lock.  At this point the client
still gets back EACCES, which is an issue we're still working.

4b4ec9b800 Fix boundry condition in lock management:
Alfred, I took a look at retry_blockingfilelocklist() and the
 solution seemed  simple enough. Please correct me if I am wrong.
 It seems said routine doesn't  take into account boundary conditions
 when putting back file_lock entries into the blocked lock-list.
 Specifically, it fails when the file_lock being put back is the
 last element in the list, and when it is the only element in the
 list.  I've included a patch below.

 Basically, it introduces another variable: pfl, which keeps track
 of the list  item before ifl. That way if nfl is NULL, ifl gets
 inserted after pfl. If pfl  is also NULL, then it gets inserted
 at the head of the list (since it was the  only element in the
 list).

5f07c7b294 This completes the all partial file locking under NFS. The underlying
file is still completely covered by a flock(2) style lock, but we'll tackle
that at a later date.

b6dc41baf1 Cleanup.
use LIST_FOREACH,

add prototypes (functions should be made static probably),

change DEBUG=1 to LOCKD_DEBUG,

K&R function instantiation for functions with long args lists,

Move comments about functions from within to above the function,

Simplified some if/else logic and reduced nested blocks.

parens around 'return' argument (return FOO -> return (FOO))

7e589b0b6e This adds in the full HW locking capability and should now make my rewrite
of the rpc.lockd fully compliant with the old file locking semantics.

Andrew will dig into the statd code next and then will attack the split
locking.

This also backs out a lot of the work I've done on making the code
more conformant with non-written style rules, but we'll revisit that
later.
