Subject: Log the errno value if seccomp_load() fails.
X-Git-Tag: tor-0.2.5.5-alpha~38^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=f0945ac270d08da146b415513fc68c7782f071be;p=thirdparty%2Ftor.git

Log the errno value if seccomp_load() fails.

(This is how I found out I was trying to test with a kernel too old
for seccomp. I think.)
