Subject: [PATCH 0/2] Enable polling on stackable devices
Date: Sat, 25 Jan 2020 21:41:36 -0700 [thread overview]
Message-ID: <20200126044138.5066-1-andrzej.jakowski@linux.intel.com> (raw)
IO polling is available on blk-mq devices. Currently it is not possible to
perform IO polling on stackable devices like MD.
We have built a prototype exposing new function for bio devices to do IO
polling on them. That function is in available on request_queue so bio based
drivers can provide handler for it.
IO polling has been provided for RAID-0 level for MD.
Andrzej Jakowski (2):
block: introduce polling on bio level
md: enable io polling
