67 bool "Single threaded compression"
116 ZLIB compression is the standard compression used by Squashfs
117 file systems. It offers a good trade-off between compression
129 compressed with LZ4 compression. LZ4 compression is mainly
133 LZ4 is not the standard compression used in Squashfs and so most
144 compressed with LZO compression. LZO compression is mainly
