* Initial DDF support code.Dan Williams2008-05-151-0/+1987
| | | | | | | | | | | | | | | | | | | | | | | Create a ddf array by naming the device /dev/ddf* or specifying metadata 'ddf'. If ddf is specified with no level, assume a container (indeed, anything else would be wrong). **Need to use text_Version to set external metadata... More ddf support Load a ddf container. Now --examine /dev/ddf works. super-ddf: fix compile warning From: Dan Williams <dan.j.williams@intel.com> super-ddf.c:723: format %lu expects type long unsigned int, but argument 3 has type unsigned int Signed-off-by: Dan Williams <dan.j.williams@intel.com>

* Fix problem with add a device to a 1.x array created with older mdadm.Neil Brown2007-08-201-0/+0
When adding new disk to an array, don't reserve so much bitmap space that the disk cannot store the required data. (Needed when 1.x array was created with older mdadm).
