      fs/squashfs: fix reading of fragmented files · 0008d808
      Joao Marcos Costa authored
      
      
      The fragmented files were not correctly read because of two issues:
      
      - The squashfs_file_info struct has a field named 'comp', which tells if
      the file's fragment is compressed or not. This field was always set to
      'true' in sqfs_get_regfile_info and sqfs_get_lregfile_info. It should
      actually take sqfs_frag_lookup's return value. This patch addresses
      these two assignments.
      
      - In sqfs_read, the fragments (compressed or not) were copied to the
      output buffer through a for loop which was reading data at the wrong
      offset. Replace these loops by equivalent calls to memcpy, with the
      right parameters.
      
      I tested this patch by comparing the MD5 checksum of a few fragmented
      files with the respective md5sum output in sandbox, considering both
      compressed and uncompressed fragments.
