1 2This directory contains various files derived from CDDL sources that 3are used by the ZFS bootstrap: 4 5 fletcher.c checksum support 6 sha256.c checksum support 7 gzip.c compression support 8 lz4.c compression support 9 lzjb.c compression support 10 blkptr.c ZFS embedded-data block pointers support 11 zfssubr.c checksum, compression and raidz support 12 zfsimpl.h mostly describing the physical layout 13 14The files fletcher.c, lzjb.c, lz4.c, sha256.c and blkptr.c are largely identical 15to the ZFS base code (with write support removed) and could be shared but that 16might complicate future imports from Illumos. 17
