Hi Kumar,
I have sent a standalone prerequisite fix for the pre-existing
issue:
LoongArch: BPF: Fix off-by-one error for insn_is_cast_user
https://lore.kernel.org/loongarch/20260828075100.24776-1-yangtiezhu@loongson.cn/
IMO, when you respin, please rebase your patches 07, 08, and 09
on top of this fix for your v2 series.
Additionally, please send the v2 as a standalone series to the
loongarch mailing list loongarch@lists.linux.dev and the reviewer
Hengqi Chen <hengqi.chen@gmail.com> too, as the LoongArch BPF JIT
patches are typically routed through the loongarch-next tree.
https://lore.kernel.org/loongarch/CAAhV-H55YcyXRewC+0YzTHXb1jab0GkAV13EF9nFbTx=UkX4ww@mail.gmail.com/
Thanks,
Tiezhu
