dm: allow offline devices

2007-05-09T19:30:47+00:00

Allow check_device_area to succeed if a device has an i_size of zero. This addresses an issue seen on DASD devices setting up a multipath table for paths in online and offline state.

[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. Signed-off-by: Bryn Reeves Signed-off-by: Alasdair G Kergon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[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. Signed-off-by: Bryn Reeves Signed-off-by: Alasdair G Kergon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[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: improve error message consistency

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

Tidy device-mapper error messages to include context information automatically. Signed-off-by: Alasdair G Kergon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] dm: create error table

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

Add a library function dm_create_error_table() to create a table that rejects any I/O sent to a device with EIO. Signed-off-by: Alasdair G Kergon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] dm table split_args: handle no input

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

Return sense if dm_split_args is called with a NULL input parameter. Signed-off-by: David Teigland Signed-off-by: Alasdair G Kergon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] dm table: get_target: fix last index

2006-06-26T16:58:35+00:00

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.) Signed-off-by: Milan Broz Signed-off-by: Alasdair G Kergon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] sem2mutex: drivers/md

2006-03-27T16:45:03+00:00

Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well. Signed-off-by: Arjan van de Ven Signed-off-by: Ingo Molnar Cc: Neil Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] dm/md dependency tree in sysfs: dm to use bd_claim_by_disk

2006-03-27T16:45:00+00:00

Use bd_claim_by_disk. Following symlinks are created if dm-0 maps to sda: /sys/block/dm-0/slaves/sda --> /sys/block/sda /sys/block/sda/holders/dm-0 --> /sys/block/dm-0 Signed-off-by: Jun'ichi Nomura Cc: Alasdair G Kergon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
