Author: sobomax Date: Wed Nov 7 16:28:09 2018 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).
