[v3,0/4] xen: debugtrace cleanup and per-cpu buffer support

Message

Juergen Gross Aug. 28, 2019, 8 a.m. UTC

Another debugtrace enhancement I needed for core scheduling debugging,
plus some cleanup.

Changes in V3:
- rebase to current staging

Changes in V2:
- added new patch 1 (preparing the move of debugtrace coding)
- patch 4 (v1 patch 3): avoid leaking buffer

Juergen Gross (4):
  xen: use common output function in debugtrace
  xen: move debugtrace coding to common/debugtrace.c
  xen: refactor debugtrace data
  xen: add per-cpu buffer option to debugtrace
