I don't know what replaces it. Ted, I am including a patch against e2fsprogs's "maint" branch to fix the build on the future FreeBSD 11+ versions. Please apply. Ian, Warner, *, I think I've got a hold of this; the replacement appears to be DIOCGMEDIASIZE from <sys/disk.h>, and has been for more than a decade, so that I had forgotten about it. The e2fsprogs port has been using DIOCGMEDIASIZE for many years (phk added DIOCGMEDIASIZE on 2002-04-08, I added upstream support 2003-12-28 but it underwent a few revisions, not worth bothering IMO) judging from the source code comments, but one of the two getsize.c source files - the one in lib/blkid/ - lacks an #ifdef DIOCGDINFO guard and relies on #ifdef HAVE_SYS_DISKLABEL_H only and jams the build. The other one in lib/ext2fs/ had a guard that checked the actual ioctl #define. Fix has been committed without Git markup in the FreeBSD ports tree, r376742. Thanks everybody.

The replacement DIOCGMEDIASIZE has been in e2fsprogs since end of 2003, but now the removal of the upstream system breaks the lib/blkid/getsize.c build. lib/ext2fs/getsize.c was unaffected because it had already been checking if this ioctl symbol was #defined. I haven't checked the situation on other BSDs, thus I am not sure if others have DIOCGMEDIASIZE, so I propose to leave the DIOCGDINFO in. Further cleanup opportunity: consolidate lib/blkid/getsize.c and lib/ext2fs/getsize.c.
