From: Omar Sandoval <[email protected]> When I moved the blk-mq debugging information to debugfs, I didn't realize that blktrace also created directories in debugfs that conflicted with the blk-mq directories. This series fixes that.
Patch 1 adds a new debugfs helper needed for patch 6. Greg, could I get an ack on that if it makes sense? Jens and I went back and forth on this for a little while, but patch 6 has more of the rationale on why we decided that this approach was the cleanest. Patches 2 and 3 are cleanups. Patch 4 is the first part of the fix, making blk-mq and blktrace use the same top-level "block" directory. Patches 5 and 6 make blk-mq and blktrace play nicely with each other w.r.t. the debugfs "block/$dev" directories. I tested this with multiple configurations, so hopefully I didn't mess that up this time. Applies to for-4.11/block. Thanks!
