sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

significant clean up and optimizations: - don't call bioq_disksort() on every command, the hardware will do that for us. - remove all of the complicated bio deferral code. bio's that can't be serviced immediately can just wait on the bioq. - Only reserve one command object for doing control commands to the card. This simplifies a lot of code and significantly reduces the size of the command struct. - Allocate commands out of a slab instead of embedding them into the softc. - Call the command action method directly instead of having ips_get_free_cmd() call it indirectly.

Change the disk(9) API in order to make device removal more robust.

2004-02-18T21:36:53Z

Previously the "struct disk" were owned by the device driver and this gave us problems when the device disappared and the users of that device were not immediately disappearing. Now the struct disk is allocate with a new call, disk_alloc() and owned by geom_disk and just abandonned by the device driver when disk_create() is called. Unfortunately, this results in a ton of "s/\./->/" changes to device drivers. Since I'm doing the sweep anyway, a couple of other API improvements have been carried out at the same time: The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to DISKFLAG_NEEDSGIANT A version number have been added to disk_create() so that we can detect, report and ignore binary drivers with old ABI in the future. Manual page update to follow shortly.
