Subject: tools/virtio: pass KCFLAGS to module build
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4e949e77fa5e335ff32f177fd37d3e469fd396f9;p=thirdparty%2Fkernel%2Flinux.git

tools/virtio: pass KCFLAGS to module build

Update the mod target to pass KCFLAGS with the in-tree vhost driver
include path. This way vhost_test can find vhost headers.

Created using Cursor CLI.
