| |
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through.
This patch fixes the following warning:
kernel/trace/trace_events_filter.c: In function ‘predicate_parse’: kernel/trace/trace_events_filter.c:494:8: warning: this statement may fall through [-Wimplicit-fallthrough=] if (next[1] == next[0]) { ^ kernel/trace/trace_events_filter.c:498:4: note: here default: ^~~~~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
