Subject: testsuite: add trap to stat() and friends including tests
X-Git-Tag: v5~66
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1426a613fa172604a4a3321238fdc6e53017f610;p=thirdparty%2Fkmod.git

testsuite: add trap to stat() and friends including tests

Add trap to stat(): we need to trap other functions too, depending on
stat.h, the function from glibc that is actually called may be stat64 or
__xstat() too.
