We can use machdep->pagesize here, so how about this? - machdep->section_size_bits = _SECTION_SIZE_BITS; + if (THIS_KERNEL_VERSION >= LINUX(5,12,0)) { + if (machdep->pagesize == 65536) + machdep->section_size_bits = 29; + else + machdep->section_size_bits = 27; + } else + machdep->section_size_bits = _SECTION_SIZE_BITS; Thanks, Kazu -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/crash-utility
