From c3036021c7bd488a382ebb15bd48225941a8686e Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 9 May 2018 09:54:07 +0200 Subject: block: use GFP_NOIO instead of __GFP_DIRECT_RECLAIM We just can't do I/O when doing block layer requests allocations, so use GFP_NOIO instead of the even more limited __GFP_DIRECT_RECLAIM.
