    Subject[PATCH v4 18/24] udf: use little-endian bitops
    As a preparation for removing ext2 non-atomic bit operations from
    asm/bitops.h. This converts ext2 non-atomic bit operations to
    little-endian bit operations.

    Change from v3:
    - change to the post-fix notation e.g. s/test_le_bit/test_bit_le/

    The whole series is available in the git repository at:
    git:// le-bitops-v4
