Subject: libmount: don't return root if path contains // or ending /
X-Git-Tag: v2.26-rc1~433
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=41510d26ddd9a4c83f8589dded539e2985535dcf;p=thirdparty%2Futil-linux.git

libmount: don't return root if path contains // or ending /

If the path fx. is /foo/bar/ the initial stripoff will replace the last slash
with \0 and return a pointer to that exact \0 character. The same thing will
happen if the path contains // somewhere.
