    Subject[PATCH 5.15 039/667] btrfs: add "0x" prefix for unsupported optional features
    Date
    From: Qu Wenruo <wqu@suse.com>

    commit d5321a0fa8bc49f11bea0b470800962c17d92d8f upstream.

    The following error message lack the "0x" obviously:

    cannot mount because of unsupported optional features (4000)

    Add the prefix to make it less confusing. This can happen on older
    kernels that try to mount a filesystem with newer features so it makes
    sense to backport to older trees.
