Subject: [PATCH bpf-next v2 0/2] bpf, x86: inline bpf_get_current_task() for x86_64
Date: Sun,  4 Jan 2026 21:16:33 +0800	[thread overview]
Message-ID: <20260104131635.27621-1-dongml2@chinatelecom.cn> (raw)

Inline bpf_get_current_task() and bpf_get_current_task_btf() for x86_64
to obtain better performance, and add the testcase for it.

Changes since v1:
- add the testcase
- remove the usage of const_current_task

Menglong Dong (2):
  bpf, x86: inline bpf_get_current_task() for x86_64
  selftests/bpf: test the jited inline of bpf_get_current_task
