Subject: lib: fix setns() function when !HAVE_SETNS
X-Git-Tag: v3.19.0~13
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1ff6b16e2d5b291fd3cc5405c492d9b27d596d0a;p=thirdparty%2Fiproute2.git

lib: fix setns() function when !HAVE_SETNS

When HAVE_SETNS is not set, iproute2 provides a local implementation of this
function based on __NR_setns.
This macro is defined in sys/syscall.h, which was not included, thus the local
implementation always returned -1.
