Subject: [PATCH bpf-next 4/5] selftests/bpf: Update bpf_cpumask_any* tests to use bpf_cpumask_any_distribute*
Date:   Fri,  9 Jun 2023 22:50:52 -0500
Message-Id: <20230610035053.117605-4-void@manifault.com>

In a prior patch, we removed the bpf_cpumask_any() and
bpf_cpumask_any_and() kfuncs, and replaced them with
bpf_cpumask_any_distribute() and bpf_cpumask_any_distribute_and().
The advertised semantics between the two kfuncs were identical, with the
former always returning the first CPU, and the latter actually returning
any CPU.

This patch updates the selftests for these kfuncs to use the new names.
