Subject: lib/procutils: reset errno before strtol() call
X-Git-Tag: v2.25-rc1~244^2~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5889fbe592457afa51da684df9337f1588469ffa;p=thirdparty%2Futil-linux.git

lib/procutils: reset errno before strtol() call

When going through /proc the last entry made readdir() to alter errno,
which made the strtol() to think something went wrong, resulting kill(1)
tests to fail when running in --parallel mode.
