| Subject: perf top: Use __fallthrough |
| |
| commit 7b0214b702ad8e124e039a317beeebb3f020d125 upstream. |
| |
| The implicit fall through case label here is intended, so let us inform |
| that to gcc >= 7: |
| |
| CC /tmp/build/perf/builtin-top.o |
| builtin-top.c: In function 'display_thread': |
| builtin-top.c:644:7: error: this statement may fall through [-Werror=implicit-fallthrough=] |
| if (errno == EINTR) |
| ^ |
| builtin-top.c:647:3: note: here |
| default: |
| ^~~~~~~ |
