Subject: [PATCH bpf-next 0/2] Small API fix for bpf_wq
Date: Fri, 05 Jul 2024 15:44:51 +0200 [thread overview]
Message-ID: <20240705-fix-wq-v1-0-91b4d82cd825@kernel.org> (raw)
I realized this while having a map containing both a struct bpf_timer and
a struct bpf_wq: the third argument provided to the bpf_wq callback is
not the struct bpf_wq pointer itself, but the pointer to the value in
the map.
Which means that the users need to double cast the provided "value" as
this is not a struct bpf_wq *.
This is a change of API, but there doesn't seem to be much users of bpf_wq
right now, so we should be able to go with this right now.
