svn commit: r269086 - in head/sys/cddl/contrib/opensolaris/uts/common/fs/zfs: . sys

[Xin LI]

Author: delphij
Date: Fri Jul 25 06:53:20 2014
New Revision: 269086
URL: http://svnweb.freebsd.org/changeset/base/269086

Log:
  As of r268075, the responsibility of rounding up buffer to optimal size have
  been transferred from zio_compress_data to its caller.  Therefore, passing
  the 'minblocksize' down will be a no-op.
  
  Eliminate the parameter to reduce diff against upstream.
