Subject: CLEANUP: src/cpuset.c: fix missing return in functions returning int
X-Git-Url: http://www.kaiwu.me/postgresql/commit//%22%22?a=commitdiff_plain;h=d9a7ff9b6c2b1dbbcb3ef1532ec3d38259638537;p=haproxy.git

CLEANUP: src/cpuset.c: fix missing return in functions returning int

Cppcheck found the issue described in github #2124, which can cause these
errors if no CPUSET implementation is supported (and CPUSET_USE_ULONG is
not enabled):

src/cpuset.c:21:11: error: Found an exit path from function with non-void return type that has missing return statement [missingReturn]
src/cpuset.c:36:11: error: Found an exit path from function with non-void return type that has missing return statement [missingReturn]
src/cpuset.c:100:1: error: Found an exit path from function with non-void return type that has missing return statement [missingReturn]
src/cpuset.c:124:1: error: Found an exit path from function with non-void return type that has missing return statement [missingReturn]
src/cpuset.c:152:1: error: Found an exit path from function with non-void return type that has missing return statement [missingReturn]
src/cpuset.c:163:1: error: Found an exit path from function with non-void return type that has missing return statement [missingReturn]

This can be backported.
