    ovl: simplify ovl_same_sb() helper · 0f831ec8
    Amir Goldstein authored
    No code uses the sb returned from this helper, so make it retrun a boolean
    and rename it to ovl_same_fs().
    
    The xino mode is irrelevant when all layers are on same fs, so instead of
    describing samefs with mode OVL_XINO_OFF, use a new xino_mode state, which
    is 0 in the case of samefs, -1 in the case of xino=off and > 0 with xino
    enabled.
    
    Create a new helper ovl_same_dev(), to use instead of the common check for
    (ovl_same_fs() || xinobits).
