[PATCH 1/4] ocfs2/dlm: Retract fix for race between purge and migrate
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.

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

[PATCH 1/1] ocfs2-devel: trivial fix for s/migrate/migration/ in dlmrecovery.c, line 1121
in dlmrecovery.c:1121, replace 'migrate' to 'migration' to keep the consistency
by comparing to other lines with the similar log info in the same file.

[BUG] ocfs2/dlm: possible data races in dlm_drop_lockres_ref_done() and dlm_get_lock_resource()
Hello,
Our static analysis tool finds some possible data races in the OCFS2 file
system in Linux 6.4.0-rc6.
In most calling contexts, the variables such as res->lockname.name and
res->owner are accessed with holding the lock res->spinlock. Here is an
example:
lockres_seq_start() --> Line 539 in dlmdebug.c
spin_lock(&res->spinlock); --> Line 574 in dlmdebug.c (Lock

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.

One node hangs up issue requiring goog idea, thanks
Hi, all,
As we use OCFS2, the network is not good.
When the converting request message can?t send to the another node, there will be a node hangs up which will still waiting for the dlm.

[git patches] Ocfs2 updates for 2.6.30
Hi,
The following patches comprise the bulk of Ocfs2 updates for the
2.6.30 merge window. Aside from larger, more involved fixes, we're adding
the following features, which I will describe in the order their patches are
mailed.
Sunil's exported some more state to our debugfs files, and
consolidated some other aspects of our debugfs infrastructure. This will
further aid us in debugging

[PATCH 0/62] Ocfs2 updates for 2.6.26-rc1
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

[PATCH 2/5] ocfs2/dlm: add lockres as parameter to dlm_new_lock()
Wether the dlm_lock needs to access lvb or not depends on dlm_lock_resource it belongs to. So a new parameter "struct dlm_lock_resource *res" is added to dlm_new_lock() so that we can know if we need to allocate lvb for the dlm_lock. And we have to make the lockres availale for calling dlm_new_lock().

[PATCH 1/1] OCFS2: fix for nfs getting stale inode.
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),

[PATCH] ocfs2: Plugs race between the dc thread and an unlock ast message
This patch plugs a race between the downconvert thread and an unlock ast message.
Specifically, after the downconvert worker has done its task, the dc thread needs
to check whether an unlock ast made the downconvert moot.

[PATCH 1/1] OCFS2: timer to queue scan of all orphan slots
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.
