| |
Is there any reason why 32-bit uswsusp &Friends does not work on 64bits kernel?
For one, 32bits s2disk produces the following when trying to suspend:
ioctl32(s2disk:4134): Unknown cmd fd(4) cmd(400c330d){t:'3';sz:12} arg(ff853554) on /dev/snapshot ioctl32(s2disk:4134): Unknown cmd fd(4) cmd(4004330a){t:'3';sz:4} arg(00000805) on /dev/snapshot
this is coming from:
error = ioctl(dev, SNAPSHOT_SET_SWAP_AREA, &swap); if (error && !offset) error = ioctl(dev, SNAPSHOT_SET_SWAP_FILE, blkdev);
but I guess (just guess!) that other SNAPSHOT_* operations will also fail the same way.
Is there a reason why those are not in compat_ioctl?
Thanks.
