    SubjectRe: [PATCH 1/2] arm64: bpf: add 'store immediate' instruction
    Hi folks,

    Any more comments on this patch (store immediate only)?

    I need more time to add XADD (I'm supposed everyone agrees it is
    equivalent to atomic_add). However, this one is irrelevant to XADD, so
    we may be able to apply it first?

    Thanks,
    Yang
