Hi Joel/Srini, Here are 2 patches for orphan lock in local mode. patch 1: In local mode, we don't need lvb, so don't init it. patch 2: In local mode, orphan lock and unlock don't need to go to dlm part. Regards, Tao

David, So here are the two patches. Remove all patches that you have and apply these. The first one is straight forward. The second one will hopefully fix the livelock issue you have been encountering. People reviewing the patches should note that the second one is slightly different than the one I posted earlier. It removes the BUG_ON in the if condition where we jump to update_holders. The

Hi, All, These four patches are all related to ocfs2 on hard readonly mount. patch 1 fix oops when umount ocfs2 on hard readonly device. Because ocfs2_dismount_volume() will call ocfs2_cluster_hangup() and then call ocfs2_stack_driver_put(), will hit BUG_ON(active_stack == NULL). patch 2 fix oops when do ls or cat in ocfs2 on hard readonly device. Because ocfs2_open_lock() will call

This patch adds freeze_fs()/unfreeze_fs() for ocfs2 so that it supports freeze/thaw.

This is to avoid frequent scans.

Mainline commit d4f7e650e55af6b235871126f747da88600e8040 attempts to delay the dlm_thread from sending the drop ref message if the lockres is being migrated. The problem is that we make the dlm_thread wait for the migration to complete. This causes a deadlock as dlm_thread also participates in the lockres migration process. A better fix for the original oss bugzilla#1012 is in testing.

The Lock Value Block (LVB) of a DLM lock can be lost when nodes die and the DLM cannot reconstruct its state. Clients of the DLM need to know this. ocfs2's internal DLM, o2dlm, explicitly zeroes out the LVB when it loses track of the state. This is not a standard behavior, but ocfs2 has always relied on it. Thus, an o2dlm LVB is always "valid". ocfs2 now supports both o2dlm and

Hi, here comes the next version of OCFS2 lockdep support. I've dropped patches with fixes from the series since they were already merged. As Joel suggested, I've simplified the main patch a bit so that we don't have ifdefs around lock declarations and there are also a few other minor improvements. Honza
