Subject: [PATCH bpf 0/4] bpf_prog_pack and vmalloc-on-huge-page fixes
Date: Thu, 21 Apr 2022 22:18:09 -0700	[thread overview]
Message-ID: <20220422051813.1989257-1-song@kernel.org> (raw)

NOTE: This set is based on Linus' master branch (d569e86915b7), not
bpf/master.

There are various discussion about these changes, check out [1] [2].
I guess we can use this thread to discuss which patches should go in 5.18.
AFAICT, 1/4 need to with 5.18; 2/4 seems safe to go as well; 3/4 and 4/4
may still need more work/discussion.

Thanks!
