svn commit: r340220 - head/sys/geom

[Maxim Sobolev]

Author: sobomax

New Revision: 340220
URL: https://svnweb.freebsd.org/changeset/base/340220

Log:
  Revert r340187, it breaks EOD (end-of-device) detection logic. Turns out,
  i/o into last_sector+N is handled differently for N==1 and N>1 cases to
  accomodate that, so some other approach would be needed to fix DIOCGDELETE
  ioctl(2).
