| Subject: selftests: use -isystem instead of -I to include headers |
| |
| Selftests need kernel headers and glibc for compilation. In compilation |
| of selftests, uapi headers from kernel source are used instead of default |
| ones while glibc has already been compiled with different header files |
| installed in the operating system. So there can be redefinition warnings |
| from compiler. These warnings can be suppressed by using -isystem to |
| include the uapi headers. |
