Maintainers, ping? Hi Borislav, during the review of V4, you suggested to re-design the return value of parse_crashkernel(), the latest try is on https://lore.kernel.org/patchwork/patch/1065514/. It seems hard to move on in that thread. On the other hand, my series "[PATCHv5 0/2] x86/boot/KASLR: skip the specified crashkernel region" has no depend on the "re-design the return value of parse_crashkernel()".
