o2dlm mle hash patches - round 2
The changes from the last drop are: 1. Patch 11 removes struct dlm_lock_name. 2. Patch 12 is an unrelated bugfix. Actually is related to a bugfix that we are retracting in mainline currently. The patch may need more testing. While I did hit the condition in my testing, Marcos hasn't. I am sending it because it can be queued for 2.6.30. Give us more time to test. 3. Patch 13 will be useful

Convert mle list to a hash
These patches convert the mle list to a hash. The same patches apply on ocfs2 1.4 too. Currently, we use the same number of hash pages for mles and lockres'. This will be addressed in a future patch that will make both of them configurable. Sunil

[PATCH] Remove versioning information
The versioning information is confusing for end-users. The numbers are stuck at 1.5.0 when the tools have moved to 1.8.3. I suggest removing the versioning system in the kernel altogether and let the kernel version be the guide to debug issues. However, if you think versioning is still required, please state the reason and modify the version string in the ver.* files to reflect the uptodate

O2CB global heartbeat - hopefully final drop!
All, This is hopefully the final drop of the patches for adding global heartbeat to the o2cb stack. The diff from the previous set is here: http://oss.oracle.com/~smushran/global-hb-diff-2010-10-07 Implemented most of the suggestions provided by Joel and Wengang. The most important one was to activate the feature only at the end, Also, got mostly a clean run with checkpatch.pl. Sunil
