[PATCH] VFS: Fix memory leak with file leases
The patch
http://linux.bkbits.net:8080/linux-2.6/diffs/fs/locks.c@1.70??nav=index.html
introduced a pretty nasty memory leak in the lease code. When freeing
the lease, the code in locks_delete_lock() will correctly clean up
the fasync queue, but when we return to fcntl_setlease(), the freed
fasync entry will be reinstated.
This patch ensures that we skip the call to fasync_helper() when we're
freeing up the lease.
