  • 2021f083e   fs: btrfs: Fix unaligned memory accesses ... Browse Code »

    Loading files stored with lzo compression from a btrfs filesystem was
    producing unaligned memory accesses, which were causing a data abort
    and a reset on an Orange Pi Zero.

    The change in hash.c is not triggered by any error but follows the
    same pattern. Please confirm.

    Fixed according to doc/README.unaligned-memory-access.txt

  • 21a14facb   fs: btrfs: Add single-device read-only BTRFS implementation ... Browse Code »

    This adds the proper implementation for the BTRFS filesystem.
    The implementation currently supports only read-only mode and
    the filesystem can be only on a single device.

    Checksums of data chunks is unimplemented.

    Compression is implemented (ZLIB + LZO).
