Hi Linus,
please pull from
git+ssh://master.kernel.org/pub/scm/linux/kernel/git/ryusuke/nilfs2.git for-linus
to receive nilfs2 updates for 2.6.37.
Most part of these patches are for sanitizing inode usage and reducing
code duplication between nilfs and vfs; these remove nilfs' own inode
hash table and own inode allocator, which were used in garbage
collection cache and metadata management respectively.
Collaterally there is an internal change in terms of the way to hold
snapshots on memory. Previously, nilfs allocated an sb instance per
snapshot, and multiple sb instances could be allocated for one device.
Now all snapshots on the same device are handled with one sb, and the
relation between bdev and sb is put right.
The full patches and note are found in series "nilfs2: remove own
inode hash used for GC" and "nilfs2: remove own inode allocator" on
linux-fsdevel.
Other changes include:
* support filesystem freeze/unfreeze interface
* fix potential overflow in checkpoint number argument of "cp=<n>"
mount option which is used when mounting snapshots.
* disable compatibility check by revision level for future revisions.
(feature sets, which were integrated to the last kernel, will take
over the role).
* sparse warning fixes, and so forth.
Thanks!
Ryusuke Konishi
