NEWS: update to reflect new dependency and limitation
Browse files Browse the repository at this point in the history
Added info about dependency on libfuse (2 or 3).

Added warning that copyin(), copyinstr(), and copyinto() may not work
on some aarch64 platforms due to limitations in the BPF implementation
at the kernel level.
