From: Honglei Wang <jameshongleiwang@126.com> mainline inclusion from mainline-v6.13-rc6 commit 793baff3f24f16dab9061045e23eea67724feae6 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ID7HLY Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commi... -------------------------------- commit 5cbb302880f5 ("sched_ext: Rename scx_bpf_dispatch[_vtime]_from_dsq*() -> scx_bpf_dsq_move[_vtime]*()") introduced several new functions which caused compilation errors when compiled with clang. Let's fix this by adding __weak markers.
