This patchset make the wait_for_dev globally, it will wait for all
devices in host_devs. This not only limited to fstab and --device
passed items, such as below code, for these system mountpoint it's still
necessary to find the udev name if we want to wait them in initramfs:
push host_mp \
"/" \
"/etc" \
"/usr" \
"/usr/bin" \
"/usr/sbin" \
"/usr/lib" \
"/usr/lib64" \
"/boot"
for mp in "${host_mp[@]}"; do
mountpoint "$mp" >/dev/null 2>&1 || continue
push host_devs $(readlink -f "/dev/block/$(find_block_device
"$mp")")
done
