[Xen-devel] [PATCH 3/3] xenalyze: handle RTDS scheduler events

[Dario Faggioli <dario.faggioli@xxxxxxxxxx>]

so the trace will show properly decoded info,
rather than just a bunch of hex codes.

Changes from v2:
 * use 64 bits ints for time values (now that the scheduler
   does that too), as suggested during review.

Changes from v1:
 * '} * r =' turned into '} *r =', as requested
   during review.
