From d38499530e5f170d30f32d3841fade204e63081d Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 1 Nov 2016 07:40:11 -0600 Subject: fs: decouple READ and WRITE from the block layer ops Move READ and WRITE to kernel.h and don't define them in terms of block layer ops; they are our generic data direction indicators these days and have no more resemblance with the block layer ops.
