* Now that the sectorsize and mediasize are properties of the provider,phk2002-10-201-13/+5
| | | | | | | | | | | don't take the detour over the I/O path to discover them using getattr(), we can just pick them out directly. Do note though, that for now they are only valid after the first open of the underlying disk device due compatibility with the old disk_create() API. This will change in the future so they will always be valid. Sponsored by: DARPA & NAI Labs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | that this will make people use this for their future copy&paste operations. Rework the detection of raw-disk offsets in disklabels. This actually unearthed a number of bugs in the (now) previous version. Also accept labels which don't have a magic RAW_PART, provided they don't confuse us too much. Change the order of our sanity-checks on labels found on disks to be more robust. Check against MAXPARTITIONS in our sanity-check and reject disklabels we cannot cope with. Create new g_bsd_modify() function to implment disklabel modifying ioctls. Implement DIOCSDINFO and DIOCWDINFO with the provision that the latter still not writes your change back to disk. I didn't have the nerves for that yet. In the start routine, use g_call_me() for complex ioctls to prevent sleeping. Sponsored by: DARPA & NAI Labs.

* Introduce the concept of "magic spaces", and implement them in most ofphk2002-05-211-1/+15
| | | | | | | | | | | | | | | | the relevant classes. Some methods may implement various "magic spaces", this is reserved or magic areas on the disk, set a side for various and sundry purposes. A good example is the BSD disklabel and boot code on i386 which occupies a total of four magic spaces: boot1, the disklabel, the padding behind the disklabel and boot2. The reason we don't simply tell people to write the appropriate stuff on the underlying device is that (some of) the magic spaces might be real-time modifiable. It is for instance possible to change a disklabel while partitions are open, provided the open partitions do not get trampled in the process. Sponsored by: DARPA & NAI Labs.
