*	[PATCH] dm table: add target flush	Bryn Reeves	2006-10-03
\| \| \| \| \| \| \| \| \| \| \|	This patch adds support for a per-target dm_flush_fn method. This is needed to allow dm-loop to invalidate page cache mappings in response to BLKFLSBUF ioctl commands.

*	[PATCH] dm: extract device limit setting	Bryn Reeves	2006-10-03
\| \| \| \| \| \| \| \| \| \|	Separate the setting of device I/O limits from dm_get_device(). dm-loop will use this.

*	[PATCH] dm table: add target preresume	Milan Broz	2006-10-03
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch adds a target preresume hook. It is called before the targets are resumed and if it returns an error the resume gets cancelled. The crypt target will use this to indicate that it is unable to process I/O because no encryption key has been supplied.

*	[PATCH] dm table: get_target: fix last index	Milan Broz	2006-06-26
\| \| \| \| \| \| \| \| \| \| \| \|	The table is indexed from 0, so an index equal to t->num_targets should be rejected. (There is no code in the current tree that would exercise this bug.)

*	[SCSI] seperate max_sectors from max_hw_sectors	Mike Christie	2005-12-15
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	- export __blk_put_request and blk_execute_rq_nowait needed for async REQ_BLOCK_PC requests - seperate max_hw_sectors and max_sectors for block/scsi_ioctl.c and SG_IO bio.c helpers per Jens's last comments. Since block/scsi_ioctl.c SG_IO was already testing against max_sectors and SCSI-ml was setting max_sectors and max_hw_sectors to the same value this does not change any scsi SG_IO behavior. It only prepares ll_rw_blk.c, scsi_ioctl.c and bio.c for when SCSI-ml begins to set a valid max_hw_sectors for all LLDs. Today if a LLD does not set it SCSI-ml sets it to a safe default and some LLDs set it to a artificial low value to overcome memory and feedback issues. Note: Since we now cap max_sectors to BLK_DEF_MAX_SECTORS, which is 1024, drivers that used to call blk_queue_max_sectors with a large value of max_sectors will now see the fs requests capped to BLK_DEF_MAX_SECTORS.

*	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!
