Below is the first cut at making the block size limit configurable to 64
bits on x86, as well as always 64 bits on 64 bit machines. The audit
isn't complete yet, but a good chunk of it is done.
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/md1 7508125768 20 7476280496 1% /mnt/3
This is a 7TB ext2 filesystem on 4KB blocks. The 7TB /dev/md1 consists of
7x 1TB sparse files on loop devices raid0'd together. The current patch
does not have the fixes in the SCSI layer or IDE driver yet; expect the
SCSI fixes in the next version, although I'll need a tester. The
following should be 64 bit clean now: nbd, loop, raid0, raid1, raid5.
Ugly bits: I had to add libgcc.a to satisfy the need for 64 bit division.
Yeah, it sucks, but RAID needs some more massaging before I can remove the
64 bit division completely. This will be fixed.
Copies of this and later versions of the patch are available at
http://people.redhat.com/bcrl/lb/ and http://www.kvack.org/~blah/lb/ .
Please forward any bug fixes or comments to me. Cheers,
-ben
