Subject: move gfs2 tracepoints to inclue/trace/events dir
hi,
I'd like to move the gfs2 tracepoints to the the common
include/trace/events directory along with all of the other trace events.
It makes understanding what tracepoints are available easier, and I see
no reason why gfs2 should be different. For example, 'ext4.h' is already
in the include/trace/events directory.
thanks,
-Jason
