similar to: Patches that adds delayed orphan scan timer

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

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

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.

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

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

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, 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

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

Hi all, this patch set are the backport of inode alloc improvement from mainline to ocfs2-1.4. the patches are almost the same excpet one thing: Joel has added JBD2 support to ocfs2, so he has added "max_blocks" to alloc_context and add a new function "ocfs2_reserve_clusters_with_limit". We don't have that in ocfs2-1.4. So there are some great difference in patch 2.

The following patch is a backport of patch that recovers orphans from offline slots. It is being backported from mainline to 1.4 mainline patch: 0001-Patch-to-recover-orphans-in-offline-slots-during-rec.patch Thanks, --Srini

In ocfs2, the inode block search looks for the "emptiest" inode group to allocate from. So if an inode alloc file has many equally (or almost equally) empty groups, new inodes will tend to get spread out amongst them, which in turn can put them all over the disk. This is undesirable because directory operations on conceptually "nearby" inodes force a large number of seeks. So

Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink. For the design doc, please

During recovery, a node recovers orphans in it's slot and the dead node(s). But if the dead nodes were holding orphans in offline slots, they will be left unrecovered. If the dead node is the last one to die and is holding orphans in other slots and is the first one to mount, then it only recovers it's own slot, which leaves orphans in offline slots. This patch queues complete_recovery

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
