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_probe.c: In function ‘parse_probe_arg’: kernel/trace/trace_probe.c:302:6: warning: this statement may fall through [-Wimplicit-fallthrough=] arg++; /* Skip '+', because kstrtol() rejects it. */ ~~~^~ kernel/trace/trace_probe.c:303:2: note: here case '-': ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
