    This patchset is for updating the LZ4 compression module to a version based
    on LZ4 v1.7.2 allowing to use the fast compression algorithm aka LZ4 fast
    which provides an "acceleration" parameter as a tradeoff between
    high compression ratio and high compression speed.
    
    We want to use LZ4 fast in order to support compression in lustre
    and (mostly, based on that) investigate data reduction techniques in behalf of
    storage systems.
    
    Also, it will be useful for other users of LZ4 compression, as with LZ4 fast
    it is possible to enable applications to use fast and/or high compression
    depending on the usecase.
    For instance, ZRAM is offering a LZ4 backend and could benefit from an updated
    LZ4 in the kernel.

    v6:
    - Fixed LZ4_NBCOMMONBYTES() for 64-bit little endian
    - Reset LZ4_MEMORY_USAGE to 14 (which is the value used in
      upstream LZ4 as well as the previous kernel module)
    - Fixed that weird double-indentation in lz4defs.h and lz4.h
    - Adjusted general styling issues in lz4defs.h
      (e.g. lines consisting of more than one instruction)
    - Removed the architecture-dependent typedef to reg_t
      since upstream LZ4 is just using size_t and that works fine
    - Changed error messages in pstore/platform.c:
      * LZ4_compress_default always returns 0 in case of an error
        (no need to print the return value)
      * LZ4_decompress_safe returns a negative error message
        (return value _does_ matter)

    This patchset is for updating the LZ4 compression module to a version based
    on LZ4 v1.7.3 allowing to use the fast compression algorithm aka LZ4 fast
    which provides an "acceleration" parameter as a tradeoff between
    high compression ratio and high compression speed.
    
    We want to use LZ4 fast in order to support compression in lustre
    and (mostly, based on that) investigate data reduction techniques in behalf of
    storage systems.
    
    Also, it will be useful for other users of LZ4 compression, as with LZ4 fast
    it is possible to enable applications to use fast and/or high compression
    depending on the usecase.
    For instance, ZRAM is offering a LZ4 backend and could benefit from an updated
    LZ4 in the kernel.

    [PATCH 1/5] lib: Update LZ4 compressor module
    [PATCH 2/5] lib/decompress_unlz4: Change module to work with new LZ4 module version
    [PATCH 3/5] crypto: Change LZ4 modules to work with new LZ4 module version
    [PATCH 4/5] fs/pstore: fs/squashfs: Change usage of LZ4 to work with new LZ4 version
    [PATCH 5/5] lib/lz4: Remove back-compat wrappers
    
    Changes:
    v7:
    - Fixed errors reported by the Smatch tool
    - Changed function documentation comments in lz4.h to match kernel-doc style
    - Fixed a misbehaviour of LZ4HC caused by the wrong level of indentation
      concerning two for loops introduced after I refactored the code style using
      checkpatch.pl (upstream LZ4 put dozens of stuff in just one line, gnah)
    - Updated the crypto tests for LZ4 since they did fail for the new code
      and hence zram did fail to allocate memory for LZ4
    
    v6:
    - Fixed LZ4_NBCOMMONBYTES() for 64-bit little endian
    - Reset LZ4_MEMORY_USAGE to 14 (which is the value used in
      upstream LZ4 as well as the previous kernel module)
    - Fixed that weird double-indentation in lz4defs.h and lz4.h
    - Adjusted general styling issues in lz4defs.h
      (e.g. lines consisting of more than one instruction)
    - Removed the architecture-dependent typedef to reg_t
      since upstream LZ4 is just using size_t and that works fine
    - Changed error messages in pstore/platform.c:
      * LZ4_compress_default always returns 0 in case of an error
        (no need to print the return value)
      * LZ4_decompress_safe returns a negative error message
        (return value _does_ matter)
    
    v5:
    - Added a fifth patch to remove the back-compat wrappers introduced
      to ensure bisectibility between the patches (the functions are no longer
      needed since there's no callers left)
    
    v4:
    - Fixed kbuild errors
    - Re-added lz4_compressbound as alias for LZ4_compressBound
      to ensure backwards compatibility
    - Wrapped LZ4_hash5 with check for LZ4_ARCH64 since it is only used there
      and triggers an unused function warning when false
    
    v3:
    - Adjusted the code to satisfy kernel coding style (checkpatch.pl)
    - Made sure the changes to LZ4 in Kernel (overflow checks etc.)
      are included in the new module (they are)
    - Removed the second LZ4_compressBound function with related name but
      different return type
    - Corrected version number (was LZ4 1.7.3)
    - Added missing LZ4 streaming functions
    
    v2:
    - Changed order of the patches since in the initial patchset the lz4.h was in the
      last patch but was referenced by the other ones
    - Split lib/decompress_unlz4.c in an own patch
    - Fixed errors reported by the buildbot
    - Further refactorings
    - Added more appropriate copyright note to include/linux/lz4.h
