Subject: [PATCH 5.10 21/97] tools/virtio: compile with -pthread
Date: Mon, 23 May 2022 19:05:25 +0200	[thread overview]
Message-ID: <20220523165815.629891303@linuxfoundation.org> (raw)
In-Reply-To: <20220523165812.244140613@linuxfoundation.org>

From: Michael S. Tsirkin <mst@redhat.com>

[ Upstream commit f03560a57c1f60db6ac23ffd9714e1c69e2f95c7 ]

When using pthreads, one has to compile and link with -lpthread,
otherwise e.g. glibc is not guaranteed to be reentrant.

This replaces -lpthread.
