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).
