[PATCH v2 0/2] trace-vmscan-postprocess: fix parsing and output

From: Florian Schmidt
Date: Wed Sep 11 2019 - 07:12:13 EST

This patch series updates trace-vmscan-postprocess.pl to work without
throwing warnings and errors which stem from updates to several trace

3481c37ffa1d ("mm/vmscan: drop may_writepage and classzone_idx from
direct reclaim begin template") removed "may_writepage" from
mm_vmscan_direct_reclaim_begin, and 3b775998eca7
("include/trace/events/vmscan.h: drop zone id from kswapd tracepoints")
removed "zid" from mm_vmscan_wakeup_kswapd. The output of
mm_vmscan_lru_isolate and mm_vmscan_lru_shrink_active seems to never
have matched the format of the trace point output since they were
created, or at least for as long as I can tell. Patch 1 aligns the
format parsing of the perl script with the current output of the trace

In addition, the tables that are printed by the script were not properly
aligned any more, so patch 2 fixes the spacing.

Changes since v1:
* Added "Fixes:" lines to commit meessage in patch 1
* Fixed a spacing issue in patch 2

Florian Schmidt (2):
trace-vmscan-postprocess: sync with tracepoints updates
trace-vmscan-postprocess: fix output table spacing
