Linus,

please pull UBIFS from 'for_linus' branch of

git://git.infradead.org/~dedekind/ubifs-2.6.git for_linus

UBIFS has been in -mm tree for about 3 months and in -next tree for about 2
month. There were 3 LKML submission rounds:

http://marc.info/?l=linux-kernel&m=121180458401234&w=2

Please, refer the following URLs for UBIFS introduction (sorted in
brief->longer order):

1. First UBIFS submission:
http://marc.info/?l=linux-kernel&m=120662475821992&w=2
2. Jonathan Corbet's article:
http://lwn.net/Articles/276025/
3. Documentation and FAQ at the MTD web site:

http://www.linux-mtd.infradead.org/faq/ubi.html
4. UBIFS white-paper:
http://www.linux-mtd.infradead.org/doc/ubifs_whitepaper.pdf

For the last 2 months we've been stabilizing UBIFS and its on-flash format
and we think it is production-ready and may be merged. We are going to
keep developing and maintain it.

We use UBIFS in Nokia and we also have several community users, e.g.:
http://lists.infradead.org/pipermail/linux-mtd/2008-May/021801.html

We have positive feed-backs, e.g.:

VFS: export sync_sb_inodes

This patch exports the 'sync_sb_inodes()' which is needed for
UBIFS because it has to force write-back from time to time.
Namely, the UBIFS budgeting subsystem forces write-back when
its pessimistic callculations show that there is no free
space on the media.

VFS: move inode_lock into sync_sb_inodes

This patch makes 'sync_sb_inodes()' lock 'inode_lock', rather
than expect that the caller will do this.

This change was previously done by Hans Reiser <reiser@xxxxxxxxxxx>
and sat in the -mm tree.

======================================================================

The non-UBIFS patches are short and rather trivial, so we inline them. The UBIFS
patches are big, so we only provide stats.
