Subject: fix confusion around GFP_* flags and blk_get_request
Date: Wed, 9 May 2018 09:54:02 +0200 [thread overview]
Message-ID: <20180509075408.16388-1-hch@lst.de> (raw)
Hi all,
this series sorts out the mess around how we use gfp flags in the
block layer get_request interface.
Changes since RFC:
- don't switch to GFP_NOIO for allocations in blk_get_request.
blk_get_request is used by the multipath code in potentially dead lock
prone areas, so this will need a separate audit and maybe a flag.
