From 67688c08b7e5e9f8f945b22fb460a31ed3feb880 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 14 Jul 2022 11:07:19 -0700 Subject: fs/gfs2: Use the enum req_op and blk_opf_t types Improve static type checking by using the enum req_op type for variables that represent a request operation and the new blk_opf_t type for variables that represent request flags. Combine the first two gfs2_submit_bhs() arguments into a single argument.
