From 18fbda91c6370d520278db9ee1e768b59ef5c4ab Mon Sep 17 00:00:00 2001 From: Omar Sandoval Date: Tue, 31 Jan 2017 14:53:20 -0800 Subject: block: use same block debugfs directory for blk-mq and blktrace When I added the blk-mq debugging information to debugfs, I didn't notice that blktrace also creates a "block" directory in debugfs. Make them use the same dentry, now created in the core block code. Based on a patch from Jens.
