Subject: [PATCH 0/3] bpf: kernel/bpf/task_iter.c: don't abuse next_thread()
Date: Tue, 14 Nov 2023 17:32:11 +0100 [thread overview]
Message-ID: <20231114163211.GA874@redhat.com> (raw)
Compile tested.
Every lockless usage of next_thread() was wrong, bpf/task_iter.c is
the last user and is no exception.
Oleg.
