![]() This is a suboptimal solution to CAS on top of MD RAID1 device. If using only submit_bio API RAID1 would process all IOs in single thread. Plugging bypasses this thread and processess IOs in blk_finish_plug caller context improving performance drastically. Testing showed no negative impact to other usecases and it's a thing that Linux does in AIO, so it's vetted and proven to work. Signed-off-by: Jan Musial <jan.musial@intel.com> |
