From 28a8f0d317bf225ff15008f5dd66ae16242dd843 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Sun, 5 Jun 2016 14:32:25 -0500 Subject: block, drivers, fs: rename REQ_FLUSH to REQ_PREFLUSH To avoid confusion between REQ_OP_FLUSH, which is handled by request_fn drivers, and upper layers requesting the block layer perform a flush sequence along with possibly a WRITE, this patch renames REQ_FLUSH to REQ_PREFLUSH.
