Author: bcr (doc committer) Date: Wed Apr 27 15:48:47 2016 New Revision: 298705 URL: https://svnweb.freebsd.org/changeset/base/298705 Log: MFC r298522: The default value of MINFREE is defined to be 8% in ufs/ffs/fs.h and not 10%. The newfs(8) and tunefs(8) man pages had this change already, but fs(5) did not. This change makes it consistent again. Bump Dd.
