[Ocfs2-devel] [git patches] Ocfs2 patches for merge window, batch 1/3

[Mark Fasheh]

Hi,

As of right now, the upstream-linus branch in ocfs2.git has 136 patches for
the next merge window. Luckily, a large chunk of those are either small or
easily read. Also, many of them are generic quota changes (which already
have appropriate review and signoffs) which I carried in ocfs2.git because
Ocfs2 quotas depended on them.

Regardless, I plan to post the ocfs2 merge window patches in 3 batches to
make review easier. The first set of patches follows this mail. The final
two will be sent early next week and will include the generic quota patches.

Aside from some xattr cleanups and fixes, these patches include supoprt for
POSIX ACLs and security attributes. These are implemented as special
extended attributes in a similar manner to other file systems.

2.6.28 added Ocfs2 support for JBD2, and made it the default. A patch is in
here which drops support for JBD completely from Ocfs2. This should make
coding up new features easier as we only have one journaling layer to
target. Users will see no difference as JBD2 is already backwards
compatible with JBD formatted journals.

The other set of cleanups in this series is to our meta data I/O paths. Joel
did a lot of work to seperate those paths into block specific calls (with an
appropriate generic helper). This not only reduced arguments at each call
site, but it allowed us to do more efficient checking for corrupted meta
data. In the 3rd round, these internal hooks will be used to enable meta
data checksums on Ocfs2.
