Message-ID: <20200727184506.2279656-33-guro@fb.com>
Date: Mon, 27 Jul 2020 11:45:03 -0700
From: Roman Gushchin <guro@...com>
To: <bpf@...r.kernel.org>
CC: <netdev@...r.kernel.org>, Alexei Starovoitov <ast@...nel.org>,

Subject: [PATCH bpf-next v2 32/35] bpf: selftests: delete bpf_rlimit.h
As rlimit-based memory accounting is not used by bpf anymore,
there are no more reasons to play with memlock rlimit.
Delete bpf_rlimit.h which contained a code to bump the limit.
Signed-off-by: Roman Gushchin <guro@...com>
