26bcbf965f lockd: stop abusing file_lock_list
Currently lockd directly access the file_lock_list from fs/locks.c.
It does so to mark locks granted or reclaimable.  This is very
suboptimal, because a) lockd needs to poke into locks.c internals, and
b) it needs to iterate over all locks in the system for marking locks
granted or reclaimable.

This patch adds lists for granted and reclaimable locks to the nlm_host
structure instead, and adds locks to those.

nlmclnt_lock:
	now adds the lock to h_granted instead of setting the
	NFS_LCK_GRANTED, still O(1)

nlmclnt_mark_reclaim:
	goes away completely, replaced by a list_splice_init.
	Complexity reduced from O(locks in the system) to O(1)

reclaimer:
	iterates over h_reclaim now, complexity reduced from
	O(locks in the system) to O(locks per nlm_host)

7117bf3dfb lockd: Remove FL_LOCKD flag
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....

8dc7c3115b locks,lockd: fix race in nlmsvc_testlock
posix_test_lock() returns a pointer to a struct file_lock which is unprotected
and can be removed while in use by the caller.  Move the conflicting lock from
the return to a parameter, and copy the conflicting lock.

In most cases the caller ends up putting the copy of the conflicting lock on
the stack.  On i386, sizeof(struct file_lock) appears to be about 100 bytes.
We're assuming that's reasonable.

5ac5f9d1ce [PATCH] NLM: Fix the NLM_GRANTED callback checks
If 2 threads attached to the same process are blocking on different locks on
different files (maybe even on different servers) but have the same lock
arguments (i.e.  same offset+length - actually quite common, since most
processes try to lock the entire file) then the first GRANTED call that wakes
one up will also wake the other.

Currently when the NLM_GRANTED callback comes in, lockd walks the list of
blocked locks in search of a match to the lock that the NLM server has
granted.  Although it checks the lock pid, start and end, it fails to check
the filehandle and the server address.

By checking the filehandle and server IP address, we ensure that this only
happens if the locks truly are referencing the same file.

64a318ee2a NLM: Further cancel fixes
If the server receives an NLM cancel call and finds no waiting lock to
 cancel, then chances are the lock has already been applied, and the client
 just hadn't yet processed the NLM granted callback before it sent the
 cancel.

 The Open Group text, for example, perimts a server to return either success
 (LCK_GRANTED) or failure (LCK_DENIED) in this case.  But returning an error
 seems more helpful; the client may be able to use it to recognize that a
 race has occurred and to recover from the race.

 So, modify the relevant functions to return an error in this case.

5996a298da NLM: don't unlock on cancel requests
Currently when lockd gets an NLM_CANCEL request, it also does an unlock for
 the same range.  This is incorrect.

 The Open Group documentation says that "This procedure cancels an
 *outstanding* blocked lock request."  (Emphasis mine.)

 Also, consider a client that holds a lock on the first byte of a file, and
 requests a lock on the entire file.  If the client cancels that request
 (perhaps because the requesting process is signalled), the server shouldn't
 apply perform an unlock on the entire file, since that will also remove the
 previous lock that the client was already granted.

 Or consider a lock request that actually *downgraded* an exclusive lock to
 a shared lock.

041e0e3b19 [PATCH] fs: fix-up schedule_timeout() usage
Use schedule_timeout_{,un}interruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size.  Also use helper
functions to convert between human time units and jiffies rather than constant
HZ division to avoid rounding errors.
