[PATCH 1/3] ocfs2: Optimize inode allocation by remembering last group.
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

[PATCH 0/3] ocfs2: Inode Allocation Strategy Improvement.v2
Changelog from V1 to V2:
1. Modify some codes according to Mark's advice.
2. Attach some test statistics in the commit log of patch 3 and in
this e-mail also. See below.
Hi all,
In ocfs2, when we create a fresh file system and create inodes in it,
they are contiguous and good for readdir+stat. While if we delete all
the inodes and created again, the new inodes will get spread out and
that

[PATCH 0/3] ocfs2-1.4: Backport inode alloc from mainline.
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.

[RFC] metadata alloc fix in machines which has PAGE_SIZE > CLUSTER_SIZE
Hi Mark/Joel,
I meet with some meta allocation bugs when I implement reflink these
days. And after some investigation, I think we should have the same
problem when we have PAGE_SIZE > CLUSTER_SIZE. So I create a scenario
today in one ppc box and try. the box panic as I expected. ;)
The scenario is that: Create a file with the disk layout like this(with
bs=512, and cs=4K).

[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 1/2] JBD2: Allow feature checks before journal recovery
Before we start accessing a huge (> 16 TiB) OCFS2 volume, we need to
confirm that its journal supports 64-bit offsets. So we need to check
the journal's feature bits before recovering the journal.
This is not possible with JBD2 at present, because the journal
superblock (where the feature bits reside) is not loaded from disk until
the journal is recovered.
This patch loads the journal

[PATCH 2/2] ocfs2: add error handling path when jbd2 enter ABORT status
fstest generic cases 347 361 628 629 trigger a same issue:
When jbd2 enter ABORT status, ocfs2 ignores it and keep going to commit
journal.
This commit gives ocfs2 ability to handle jbd2 ABORT case.

[PATCH 00/42] ocfs2: Add reflink file support. V1
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.

[PATCH 0/40] ocfs2: Detach ocfs2 metadata I/O from struct inode
The following series of patches attempts to detach metadata I/O from
struct inode. They are currently tied together pretty tightly.
Metadata reads happen via the ocfs2_read_blocks() functions, writes via
both jbd2 and ocfs2_write_blocks().
- Each inode has a cache of associated metadata blocks stored on its
ip_metadata_cache member. The ocfs2_read/write_blocks() functions
take a struct

[PATCH 0/2] OCFS2 lockdep support
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.

[PATCH 1/1] OCFS2: anti stale inode for nfs (V6)
For nfs exporting, ocfs2_get_dentry() returns the dentry for fh.
ocfs2_get_dentry() may read from disk(when inode not in memory) without
any cross cluster lock. this leads to load a stale inode.
this patch fixes above problem.
solution is that in case of inode is not in memory, we get the cluster lock(PR)
of alloc inode where the inode in question is allocated from(this causes node

[PATCH 0/7] ocfs2: Directory indexing support
The following patches implement indexed directory support in Ocfs2, mostly
according to the design doc I wrote up a while ago:
http://oss.oracle.com/osswiki/OCFS2/DesignDocs/IndexedDirectories
The patches have been rebased on top of 2.6.29-rc2. It should be trivial to
put them into merge_window. Things are what I'd call complete now. I'd like
to get these into the merge_window branch

[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 0/7] OCFS2 locking fixes and lockdep annotations
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
