Subject: [PATCH] selftests/mm: on-fault-limit: run test without root privileges otherwise skip
Date: Thu,  1 Feb 2024 12:13:06 +0500	[thread overview]
Message-ID: <20240201071307.592317-1-usama.anjum@collabora.com> (raw)

The mmap() respects rlimit only for normal users. This test should be
run as normal user, without root privileges.

Fixes: b6221771d468 ("selftests/mm: run_vmtests: remove sudo and conform to tap")
