From 188bd2b16b3c6ea87a90df20f33db0adcdb75f0c Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 20 Oct 2016 15:12:11 +0200 Subject: [PATCH] block: move REQ_RAHEAD to common flags The information that am I/O is a read-ahead can be useful for drivers. In fact the NVMe driver already checks it, even if it won't ever be set at the moment.
