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 <osandov@fb.com> Augment Kconfig description. Signed-off-by: Jens Axboe <axboe@fb.com>
