svn commit: r316258 - head/sys/sys

[Konstantin Belousov]

New Revision: 316258
URL: https://svnweb.freebsd.org/changeset/base/316258

Log:
  Only activate __EXT1_VISIBLE block when using sys/errno.h in userspace.
  
  The prerequisite for '#if __EXT1_VISIBLE' functionality is the
  inclusion of sys/cdefs.h.  errno.h only auto-includes the header for
  non-kernel environment, and EXT1 block only useful for non-kernel as
  well.
