From 41d9f7cd5ba8a488fbc96350141c70c5c01bf8e6 Mon Sep 17 00:00:00 2001 From: Lars Ellenberg Date: Fri, 25 Apr 2014 13:27:50 +0200 Subject: drbd: drop drbd_md_flush The only user of drbd_md_flush was bm_rw(), and it is always followed by either a drbd_md_sync(), or an al_write_transaction(), which, if so configured, both end up submiting a FLUSH|FUA request anyways.
