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.

Best regards,
Matthias

Subject: [PATCH] Fix build on FreeBSD 11 that removes DIOCGDINFO.

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.
