Subject: lxc_init: don't fail on bad signals
X-Git-Tag: lxc-1.0.0.beta3~52
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bba1fbe695170acbe6466ed78a3b6a05a4f3a4be;p=thirdparty%2Flxc.git

lxc_init: don't fail on bad signals

Changelog: Jan 22: as Michael Warfield pointed out, we should only
ignore EINVAL, since EFAULT points to a more serious problem.
