Randy Robertson d20d5a7456 initramfs: fix initramfs to work with hardlinked init ... Change cb6ff20807 ("NOMMU: Support XIP on initramfs") seems to have broken booting from initramfs with /sbin/init being a hardlink. It seems like the logic required for XIP on nommu, i.e. ftruncate to reported cpio header file size (body_len) is broken for hardlinks, which have a reported size of 0, and the truncate thus nukes the contents of the file (in my case busybox), making boot impossible and ending with runaway loop modprobe binfmt-0000 - and of course 0000 is not a valid binary format. My fix is to only call ftruncate if size is non-zero which fixes things for me, but I'm not certain whether this will break XIP for those files on nommu systems, although I would guess not.
