[PATCH] dm table: add target flush

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

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

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

Separate the setting of device I/O limits from dm_get_device().  dm-loop will
use this.

[PATCH] dm table: add target preresume

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

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: support ioctls on mapped devices

2006-10-03T15:04:13+00:00

Extend the core device-mapper infrastructure to accept arbitrary ioctls on a
mapped device provided that it has exactly one target and it is capable of
supporting ioctls.

[We can't use unlocked_ioctl because we need 'inode': 'file' might be NULL.
Is it worth changing this?]

[PATCH] dm: create error table

Add a library function dm_create_error_table() to create a table that rejects
any I/O sent to a device with EIO.

[PATCH] dm: add exports

2006-06-26T16:58:36+00:00

Move definitions of core device-mapper functions for manipulating mapped
devices and their tables to  advertising their
availability for use elsewhere in the kernel.

Protect the contents of device-mapper.h with ifdef __KERNEL__.  And throw
in a few formatting clean-ups and extra comments.

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

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!
