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

Implemented the suggestions. Also, moved the ocfs2_orphan_scan_init() to the end of ocfs2_fill_super() instead of calling it earlier in ocfs2_initialize_super(). Sunil

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

Patch 5 has been respun with the recommended change... remove the ex argument in ocfs2_orphan_scan_lock() and ocfs2_orphan_scan_unlock(). Sunil

This patch adds jbd_lock_bh_state() and jbd_unlock_bh_state() around accessses to jh->b_committed_data.

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

The following series of patches comprises the bulk of our outstanding changes for Ocfs2. Aside from the usual set of cleanups and fixes that were inappropriate for 2.6.25, there are a few highlights: The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location meshes better with modern sysfs layout. A symbolic link has been placed in the old location so as to

All, Please review the patches backported to 1.4 from mainline. Sunil

ocfs2 currently uses the Journaled Block Device (JBD) for its journaling. This is a very stable and tested codebase. However, JBD is limited by architecture to 32bit block numbers. This means an ocfs2 filesystem is limited to 2^32 blocks. With a 4K blocksize, that's 16TB. People want larger volumes. Fortunately, there is now JBD2. JBD2 adds 64bit block number support and some other
