From 008f75a20e7072d0840ec323c39b42206f3fa8a0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 20 Oct 2021 16:41:19 +0200 Subject: block: cleanup the flush plug helpers Consolidate the various helpers into a single blk_flush_plug helper that takes a plk_plug and the from_scheduler bool and switch all callsites to call it directly. Checks that the plug is non-NULL must be performed by the caller, something that most already do anyway.
