Author: kib Date: Sun May 1 17:46:56 2016 New Revision: 298890 URL: https://svnweb.freebsd.org/changeset/base/298890
Log: Make it explicit that D_MEM cdevsw d_flag is to signify that the driver is (or behaves identically to) /dev/mem. Remove the D_MEM flag from random drivers. Note that currently the D_MEM flag does not affect any behaviour, but this going to change in the next commit.
