svn commit: r316364 - stable/11/sys/compat/linux

[Edward Tomasz Napierala]

Author: trasz
Date: Sat Apr  1 17:09:55 2017
New Revision: 316364
URL: https://svnweb.freebsd.org/changeset/base/316364

Log:
  MFC r314046:
  
  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.
