2019-02-11lightnvm: pblk: fix TRACE_INCLUDE_PATHMasahiro Yamada
As the comment block in include/trace/define_trace.h says, TRACE_INCLUDE_PATH should be a relative path to the define_trace.h ../../drivers/lightnvm is the correct relative path. ../../../drivers/lightnvm is working by coincidence because the top Makefile adds -I$(srctree)/arch/$(SRCARCH)/include as a header search path, but we should not rely on it.

2018-10-09lightnvm: pblk: add trace events for chunk statesHans Holmberg
Introduce trace points for tracking chunk states in pblk - this is useful for inspection of the entire state of the drive, and real handy for both fw and pblk debugging.
