Ilya Dryomov 8e2e2192eb blk-mq: I/O and timer unplugs are inverted in blktrace 
commit 587562d0c7 upstream.

trace_block_unplug() takes true for explicit unplugs and false for
implicit unplugs.  schedule() unplugs are implicit and should be
reported as timer unplugs.  While correct in the legacy code, this has
been inverted in blk-mq since 4.11.
