This directory contains various files derived from CDDL sources that
are used by the ZFS bootstrap:
fletcher.c checksum support
sha256.c checksum support
gzip.c compression support
lz4.c compression support
lzjb.c compression support
blkptr.c ZFS embedded-data block pointers support
zfssubr.c checksum, compression and raidz support
zfsimpl.h mostly describing the physical layout
The files fletcher.c, lzjb.c, lz4.c, sha256.c and blkptr.c are largely identical
to the ZFS base code (with write support removed) and could be shared but that
might complicate future imports from Illumos.
