Fix dm-crypt after the block cipher API changes to correctly return the
backwards compatible cipher-chainmode[-ivmode] format for "dmsetup
table".

[PATCH] separate bdi congestion functions from queue congestion functions

2006-10-20T17:26:35+00:00

Separate out the concept of "queue congestion" from "backing-dev congestion".
Congestion is a backing-dev concept, not a queue concept.

The blk_* congestion functions are retained, as wrappers around the core
backing-dev congestion functions.

This proper layering is needed so that NFS can cleanly use the congestion
functions, and so that CONFIG_BLOCK=n actually links.

2006-10-03T15:04:16+00:00

In the low memory situation dm-crypt needs to use a private mempool of bios to
avoid blocking.

[PATCH] dm crypt: move io to workqueue

2006-10-03T15:04:16+00:00

This patch is designed to help dm-crypt comply with the
new constraints imposed by the following patch in -mm:
  md-dm-reduce-stack-usage-with-stacked-block-devices.patch

Under low memory the existing implementation relies upon waiting for I/O
submitted recursively to generic_make_request() completing before the original
generic_make_request() call can return.

This patch moves the I/O submission to a workqueue so the original
generic_make_request() can return immediately.

[PATCH] dm crypt: restructure for workqueue change

2006-10-03T15:04:15+00:00

Restructure part of the dm-crypt code in preparation for workqueue changes.

Use 'base_bio' or 'clone' variable names consistently throughout.  No
functional changes are included in this patch.

[BLOCK] dm-crypt: trivial comment improvements

2006-09-21T01:46:27+00:00

Just some minor comment nits.

- little-endian is better than low-endian
- and since it is called essiv everywere it should also be essiv
  in the comments (and not ess_iv)

[BLOCK] dm-crypt: Use block ciphers where applicable

2006-09-21T01:46:13+00:00

This patch converts dm-crypt to use the new block cipher type where
applicable.  It also changes simple cipher operations to use the new
encrypt_one/decrypt_one interface.
