Subject: [PATCH AUTOSEL 5.16 20/30] tools/virtio: compile with -pthread
Date: Wed,  6 Apr 2022 21:11:30 -0400	[thread overview]
Message-ID: <20220407011140.113856-20-sashal@kernel.org> (raw)
In-Reply-To: <20220407011140.113856-1-sashal@kernel.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.
