perf/core: Mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: kernel/events/core.c: In function ‘perf_event_parse_addr_filter’: kernel/events/core.c:9154:11: warning: this statement may fall through [-Wimplicit-fallthrough=] kernel = 1; ~~~~~~~^~~ kernel/events/core.c:9156:3: note: here case IF_SRC_FILEADDR: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
