blk-mq-debugfs: get rid of a bunch of boilerplate
A large part of blk-mq-debugfs.c is file_operations and seq_file boilerplate. This sucks as is but will suck even more when schedulers can define their own debugfs entries. Factor it all out into a single blk_mq_debugfs_fops which multiplexes as needed. We store the request_queue, blk_mq_hw_ctx, or blk_mq_ctx in the parent directory dentry, which is kind of hacky, but it works. Signed-off-by:Omar Sandoval <osandov@fb.com> Reviewed-by:
