Subject: [PATCH bpf-next 04/17] selftests: xsk: set rlimit per thread
Date: Tue, 27 Jul 2021 15:17:40 +0200	[thread overview]
Message-ID: <20210727131753.10924-5-magnus.karlsson@gmail.com> (raw)
In-Reply-To: <20210727131753.10924-1-magnus.karlsson@gmail.com>

From: Magnus Karlsson <magnus.karlsson@intel.com>

Set rlimit per thread instead of on the main thread. The main thread
does not register any umem area so do not need this.
