This allows including a compression level when specifying a compression type, e.g. compression=zstd:15 Values from 1 through 15 indicate compression levels, 0 or unspecified indicates the default. For LZ4, values 3-15 specify that the HC algorithm should be used. Note that for compatibility, extents themselves only include the compression type, not the compression level. This means that specifying the same compression algorithm but different compression levels for the compression and background_compression options will have no effect. XXX: perhaps we could add a warning for this Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
