Thanks for getting back, and noted for the future. Cheers, Björn

Hi Bjorn, Yes, libbpf and selftests fixes are generally applied through bpf-next, unless the issue is pretty bad and immediate. I'm sorry, but unfortunately it's too late now to move those patches as it's now been more than a month since they landed. For the future, please let us know ASAP if you think patches were misrouted. I think we are stuck with the need to do a stable backport for these, sorry. > > RISC-V libbpf/perf needs this fix in 6.12 to properly build.

RISC-V libbpf/perf needs this fix in 6.12 to properly build. Would it be possible to have it in the bpf tree, and have it land in 6.12-rc7? Andreas that has a similar fix [1].

Ah, apologies for not stating that explicitly. It's tools/arch/riscv/include/asm/{barrier.h,fence.h} Cheers, Björn
