Author: hselasky Date: Wed Feb 21 10:13:17 2018 New Revision: 329703 URL: https://svnweb.freebsd.org/changeset/base/329703 Log: Allow LinuxKPI character devices to receive mmap() calls from the Linux binary mode user-space emulation layer. This is a regression issue after r328436, when LinuxKPI character devices started to use DTYPE_DEV in the "f_type" field of the associated file structure(s).
