* significantly simplified disklabel infrastructure. MBR handling becomes MIderaadt2007-06-171-44/+350
| | | | | | | | to support hotplug media on most architectures. disklabel setup and verification done using new helper functions. Disklabels must *always* have a correct checksum now. Same code paths are used to learn on-disk location disklabels, to avoid new errors sneaking in. Tested on almost all cases, testing help from todd, kettenis, krw, otto, dlg, robert, gwk, drahn

* The differences in the last non-homogeneous bounds_check_with_label()krw2007-06-091-1/+47
| | | | | | | | routines (alpha, vax) prove to be not worth keeping. Move bounds_check_with_label() into the MI world. Eliminate unreliable and almost certainly useless checks for overwriting a disklabel. After discussion with deraadt@

* disable a part of the label validation because some Sun systemsderaadt2007-06-041-2/+5

* Add two constraints to V1 disklabels:krw2007-06-011-15/+28
| | | | | | | | | | 1) All partitions must start before the end of the disk. 2) All partitions must end at or before the end of the disk. Partitions not satisfying these constraints will be truncated and marked FS_UNUSED. ok otto@ deraadt@
* Updated disklabel format to support larger disks and partitions. Weotto2007-05-291-1/+26
| | | | | | | | | | | free room in struct partition by packing fragment size and fragments/block more tighlty and use the resulting space to make offset and size 48 bits. For the disk part we use spare fields in struct disklabel. Kernel converts in-mem copy of the on-disk label if needed, disklabel(8) writes new version. We are careful to only change fields not used by bootloaders. Conception of basic scheme by deraadt. ok deraadt@ krw@

* Use list and queue macros where applicable to make the code easier to read;miod2004-12-261-3/+2

* This moves access to wall and uptime variables in MI code,tholo2004-06-241-17/+6
| | | | | | | | | | | | | | encapsulating all such access into wall-defined functions that makes sure locking is done as needed. It also cleans up some uses of wall time vs. uptime some places, but there is sure to be more of these needed as well, particularily in MD code. Also, many current calls to microtime() should probably be changed to getmicrotime(), or to the {,get}microuptime() versions. ok art@ deraadt@ aaron@ matthieu@ beck@ sturm@ millert@ others "Oh, that is not your problem!" from miod@

* implement new means of manipulating buf queues, bufq.tedu2003-06-251-1/+36
| | | | | | | | | | | | accessed with BUFQ macros, bufq structs support extensible, potentially changable algorithms and queue formats. the current default scheme should support nice priority based queuing, but is missing some vfs_bio.c support. only on wd.c for now, other drivers are easy converts. as a side bonus, this makes the driver code look cleaner. idea for the name comes from netbsd, but this scheme is incompatible. thanks to various people for testing. ok grange@
