*	JFS: performance patch	Sonny Rao	2005-06-23
\| \| \| \| \| \| \| \| \| \|	Basically, we saw a large amount of time spent in the jfs_strfromUCS_le() function, mispredicting the branch inside the loop, so I just added some unlikely modifiers to the if statements to re-ordered the code. Again, these simple changes provided > 2 % on spec-sfs, so please consider it for inclusion. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>

*	JFS: Fix compiler warning in jfs_logmgr.c	Dave Kleikamp	2005-06-03
\| \| \| \| \| \| \| \| \| \| \|	fs/jfs/jfs_logmgr.c: In function `jfs_flush_journal': fs/jfs/jfs_logmgr.c:1632: warning: unused variable `mp' Some debug code in jfs_flush_journal does nothing when CONFIG_JFS_DEBUG is not defined. Place the whole code segment within an ifdef to avoid unnecessary code to be compiled and the warning to be issued. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>

*	[PATCH] JFS: Don't allocate extents that overlap existing extents	Dave Kleikamp	2005-05-03
\| \| \| \| \| \| \| \| \|	Modify xtSearch so that it returns the next allocated block when the requested block is unmapped. This can be used to make sure we don't create a new extent that overlaps the next one. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
*	[PATCH] JFS: Write journal sync points more often	Dave Kleikamp	2005-05-03
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch adds jfs_syncpt, which calls lmLogSync to write sync points to the journal both in jfs_sync_fs and when sync barrier processing completes. lmLogSync accomplishes two things: 1) it pushes logged-but-dirty metadata pages to disk, and 2) it writes a sync record to the journal so that jfs_fsck doesn't need to replay more transactions than is necessary.

*	[PATCH] JFS: Support page sizes greater than 4K	Dave Kleikamp	2005-05-03
\| \| \| \| \| \| \|	jfs has never worked on architecutures where the page size was not 4K. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
*	[PATCH] JFS: Changes for larger page size	Dave Kleikamp	2005-05-03
\| \| \| \| \| \| \| \|	JFS code has always assumed a page size of 4K. This patch fixes the non-pagecache uses of pages to deal with larger pages. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
*	[PATCH] JFS: Simplify creation of new iag	Dave Kleikamp	2005-05-03
\| \| \| \| \| \| \| \| \| \| \| \| \|	JFS was creating a new IAG (inode aggregate group) in one address space, and afterwards, accessing it from another. This could lead to complications when cache pages contain more than one page of jfs metadata. This patch causes the IAG to be initialized in the same address space that it is subsequently accessed with. This also elimitates an I/O, but IAG's aren't created too often.

*	[PATCH] JFS: reduce number of synchronous transactions	Dave Kleikamp	2005-05-03
\| \| \| \| \| \| \| \| \| \|	Use an inline pxd list rather than an xad list in the xadlock. When the number of extents being modified can fit with the xadlock, a transaction can be committed asynchronously. Using a list of pxd's instead of xad's allows us to fit 4 extents, rather than 2.

*	Linux-2.6.12-rc2v2.6.12-rc2	Linus Torvalds	2005-04-16
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
