      blktrace: remove debugfs entries on bad path · fd51d251
      Stefan Raspl authored
      debugfs directory entries for devices are not removed on some
      of the failure pathes in do_blk_trace_setup().
      One way to reproduce is to start blktrace on multiple devices
      with insufficient Vmalloc space: Devices will fail with
      a message like this:
      
      	BLKTRACESETUP(2) /dev/sdu failed: 5/Input/output error
      
      If so, the respective entries in debugfs
      (e.g. /sys/kernel/debug/block/sdu) will remain and subsequent
      attempts to start blktrace on the respective devices will not
      succeed due to existing directories.

      tracing/events: Documentation updates · 143c145e
      Li Zefan authored
      - fix some typos
      - document the difference between '>' and '>>'
      - document the 'enable' toggle
      - remove section "Defining an event-enabled tracepoint", since it's
        out-dated and sample/trace_events/ already serves this purpose.
      
      v2: add "Updated by Li Zefan"
      
      [ Impact: make documentation up-to-date ]
