Subject: [PATCH] block: export trace_block_unplug


Hi Jens,
 is there any chance this can be in the next merge window?  I'm
adding block tracing to md and found I need another export.

Thanks,
NeilBrown


This allows stacked devices (like md/raid5) to provide blktrace
tracing, including unplug events.
