svn commit: r314046 - head/sys/compat/linux

[Edward Tomasz Napierala]

Author: trasz
Date: Tue Feb 21 15:57:01 2017
New Revision: 314046
URL: https://svnweb.freebsd.org/changeset/base/314046

Log:
  Get rid of foo_sys() in linuxulator code.  It was commented out, and it
  would be useless anyway - there is no point in pretending to have block
  devices; our "block" devices are in fact character ones, and can only
  be accessed as such.
  
  Discussed with:	dchagin
  MFC after:	2 weeks
  Sponsored by:	DARPA, AFRL
