Subject: [PATCH bpf-next 21/35] bpf: eliminate rlimit-based memory accounting for reuseport_array maps
Date: Fri, 24 Jul 2020 17:03:56 -0700 [thread overview]
Message-ID: <20200725000410.3566700-22-guro@fb.com> (raw)
In-Reply-To: <20200725000410.3566700-1-guro@fb.com>
Do not use rlimit-based memory accounting for reuseport_array maps.
It has been replaced with the memcg-based memory accounting.
