Hi,
Here are two more dlm patches for merging in this cycle.
commit c7be761a8163d2f1ac0b606c21e4316b7abc5af7 Author: David Teigland <teigland@redhat.com> Date: Wed Jan 7 16:50:41 2009 -0600
dlm: change rsbtbl rwlock to spinlock
The rwlock is almost always used in write mode, so there's no reason to not use a spinlock instead.

dlm: fix seq_file usage in debugfs lock dump The old code would leak iterators and leave reference counts on rsbs because it was ignoring the "stop" seq callback. The code followed an example that used the seq operations differently. This new code is based on actually understanding how the seq operations work. It also improves things by saving the hash bucket in the position to avoid cycling through completed buckets in start. Siged-off-by: Davd Teigland <teigland@redhat.com>
