From 1420c4a549bf28ffddbed827d61fb3d4d2132ddb Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 14 Jul 2022 11:07:13 -0700 Subject: fs/buffer: Combine two submit_bh() and ll_rw_block() arguments Both submit_bh() and ll_rw_block() accept a request operation type and request flags as their first two arguments. Micro-optimize these two functions by combining these first two arguments into a single argument. This patch does not change the behavior of any of the modified code.
