From ef99b2d37666b7a600baab9e1c4944436652b0a2 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 12 Oct 2021 13:12:19 +0200 Subject: block: replace the spin argument to blk_iopoll with a flags argument Switch the boolean spin argument to blk_poll to passing a set of flags instead. This will allow to control polling behavior in a more fine grained way.
