Subject: [PATCH] Fix build error on Linux >= 6.12 by guarding no_llseek

Linux 6.12 removed the no_llseek macro. Add a version check so that
.llseek = no_llseek is only used on kernels prior to 6.12.

Thanks to EricccTaiwan for the review and for pointing out that
similar cleanup could also be done in this repository.
