What do you think about > the idea to add getconf to the requirement list? CONFIG_PAGE_SHIFT was introduced in the Linux kernel in February 2024 (commit ba89f9c8ccba ("arch: consolidate existing CONFIG_PAGE_SIZE_*KB definitions")). Older kernels had CONFIG_PAGE_SIZE_4KB, CONFIG_PAGE_SIZE_16KB, etc. This means that it is possible to derive the kernel page size from the kernel configuration file for all upstream and distro kernels, isn't it? Thanks, Bart.
