This enables {gpt,}zfsboot() to allocate much larger buffers than before. - Use a larger buffer (1MB instead of 128K) for temporary ZFS buffers. Thi= s allows more reliable reading of compressed files in a raidz/raidz2 pool. Submitted by: Matt Reimer mattjreimer of gmail MFC after: 1 week Renato, are you booting ZFS? -Brandon
