dm: introduce the target flag mempool_needs_integrity

2024-07-12T16:39:06Z

This commit introduces the dm target flag mempool_needs_integrity. When the flag is set, device mapper will call bioset_integrity_create on it's bio sets. The target can then call bio_integrity_alloc on the bios allocated from the table's mempool. Signed-off-by: Mikulas Patocka Signed-off-by: Mike Snitzer

dm: optimize flushes

2024-06-26T15:32:39Z

Device mapper sends flush bios to all the targets and the targets send it to the underlying device. That may be inefficient, for example if a table contains 10 linear targets pointing to the same physical device, then device mapper would send 10 flush bios to that device - despite the fact that only one bio would be sufficient. This commit optimizes the flush behavior. It introduces a per-target variable flush_bypasses_map - it is set when the target supports flush optimization - currently, the dm-linear and dm-stripe targets support it. When all the targets in a table have flush_bypasses_map, flush_bypasses_map on the table is set. __send_empty_flush tests if the table has flush_bypasses_map - and if it has, no flush bios are sent to the targets via the "map" method and the list dm_table->devices is iterated and the flush bios are sent to each member of the list.

block: move the poll flag to queue_limits

2024-06-19T13:58:28Z

Move the poll flag into the queue_limits feature field so that it can be set atomically with the queue frozen. Stacking drivers are simplified in that they now can simply set the flag, and blk_stack_limits will clear it when the features is not supported by any of the underlying devices.
