#ifdef BSWAP_NEEDED, only FUTEX_OP_CMP_EQ and FUTEX_OP_CMP_NE will work as expected. If we want to do the rest then we'll need to implement FUTEX_OP_CMP_LT_WRONGENDIAN &c in the kernel. Or maybe, since we don't do set_robust_list (and would need wrong-endian support in the kernel for that too), we can assume that it's all in-process, and hence all _within_ qemu, and we could actually implement the futex stuff entirely within qemu with qemu's own locking? For now I think the safer option is just to leave FUTEX_WAKE_OP unimplemented. Jakub, what do you think? -- dwmw2
