Hi Horms / debian-kernel,
I found this on linux-kernel. Could you please check, whether this affects
2.6.8 and 2.4.27?

Cheers,
        Moritz

    [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.htm     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.
