[PATCH] VFS,fs/locks.c,NFSD4: add race_free posix_lock_file_conf() interface
Lockd and the NFSv4 server both exercise a race condition where
posix_test_lock() is called either before or after posix_lock_file() to
deal with a denied lock request due to a conflicting lock.
Remove the race condition for the NFSv4 server by adding a new conflicting
lock parameter to __posix_lock_file() , changing the name to
__posix_lock_file_conf().
Keep posix_lock_file() interface, add posix_lock_conf() interface, both
call __posix_lock_file_conf().
[akpm@osdl.org: Put the EXPORT_SYMBOL() where it belongs]
