From: Nathan Chancellor Date: Wed, 24 Apr 2024 17:24:09 +0000 (-0700) Subject: selftests/resctrl: ksft_exit_skip() does not return X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=47b59f3603d49d4898aafb256405b16ccdc68cc7;p=linux.git selftests/resctrl: ksft_exit_skip() does not return After commit f7d5bcd35d42 ("selftests: kselftest: Mark functions that unconditionally call exit() as __noreturn"), ksft_exit_...() functions are marked as __noreturn, which means the return type should not be 'int' but 'void' because they are not returning anything (and never were since exit() has always been called). To facilitate updating the return type of these functions, remove 'return' before the calls to ksft_exit_skip(), as __noreturn prevents the compiler from warning that a caller of ksft_exit_skip() does not return a value because the program will terminate upon calling these functions.
