similar to: [PATCH 0/2] orphan lock fixes for local mode.

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

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

Resending after implementing review comments.

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

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

Next two patches are backport of orphan scan timer patches to ocfs2-1.4

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

On unlink, all nodes check for the dentry in dcache and if present they mark the node as unlinked. The last node that purges the inode will clean it from orphan directory. When there is a memory pressure, a dentry may not be around and hence the inode is not marked as deleted and this will lead the file to be in the orphan directory till the slot is re-used during next mount. This patch initiates

Resending after adding another patch to display delayed orphan scan statistics.

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

Found 15 patches (out of 162) that appeared relevant to ocfs2 1.4. Please review. Sunil

Ocfs2 supports exporting. PROBLEM: There are 2 problems (1) Current version of ocfs2_get_dentry() may read from disk the inode WITHOUT any cross cluster lock. This may lead to load a stale inode. (2) for deleting an inode, ocfs2_remove_inode() doesn't sync/checkpoint to disk. This also may lead ocfs2_get_dentry() from other node read out stale inode. PROBLEM DETAIL: for problem (1), For

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

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have

This email is also sent to cluster-devel at redhat.com. Since this issue is about both dlm and ocfs2, I send the email here to look for help from upstream. This is an already known issue. on ocfs2 with user space cluster stack, run the test script from http://people.redhat.com/~teigland/make_panic on the mounted ocfs2 volume from 2 nodes simultaneously, the access to ocfs2 volume on both nodes

Hi, the first four patches in this series fix locking problems in OCFS2 quota code (three of them can lead to potential deadlocks). The fifth patch reorders ip_alloc_sem for directories to be acquired before localalloc locks. Mark would you please merge these? The last two patches implement lockdep annotations for OCFS2 cluster locks. We annotate all the cluster locks except for special ones

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.

Hi, I'm resending this patch series. It's rediffed against linux-next branch of Joel's git tree. The first four patches are obvious fixes of deadlocks in quota code and should go in as soon as possible. The other three patches implement lockdep support for OCFS2 cluster locks. So you can have a look whether the code make sence to you and possibly merge them. They should be NOP when
