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
