• 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

  The variable res should be initialized to 0 in these functions,

  uninitialized.

• 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).

  BTRFS on disk structures are stored in Little Endian. Add functions
  to convert this structures to cpu and to disk format.

  On Little Endian hosts, these functions do nothing.

  On Big Endian the CALL_MACRO_FROM_EACH from variadic-macro.h is used
  to define all the members for each structure on which cpu_to_le* or
  le*_to_cpu is to be called.
