From 400f73b23f457a82288814e21af57dbc9f3f2afd Mon Sep 17 00:00:00 2001 From: Omar Sandoval Date: Fri, 27 Jan 2017 15:03:01 -0700 Subject: blk-mq: fix debugfs compilation issues This fixes a couple of problems: 1. In the !CONFIG_DEBUG_FS case, the stub definitions were bogus. 2. In the !CONFIG_BLOCK case, blk-mq-debugfs.c shouldn't be compiled at all. Fix the stub definitions and add a CONFIG_BLK_DEBUG_FS Kconfig option. Fixes: 07e4fead45e6 ("blk-mq: create debugfs directory tree") Signed-off-by: Omar Sandoval Augment Kconfig description.
