| |
The following patchset breaks down the global ide_lock to per-hwgroup lock. We have taken the following approach.
1. Move the hwif tuning code from probe_hwif to ideprobe_init, after hwif_init so that hwgroups are present for all the hwifs when the tune routines for the hwifs are invoked (patch 1)
2. Change the core ide code to use hwgroup->lock instead of ide_lock. Deprecate ide_lock (patch 2)
3. Change the host controllers to use hwgroup->lock (patch 3)
4. Change host controller drivers to use per driver lock instead of ide_lock where needed or hwgroup->lock on case by case basis. This can be done incrementally for various controllers and we will have working code between patches -- this is done now for piix controller only. Eventually, we can change all controllers to remove ide_lock
Thanks to Bartlomiej for comments and suggestions.
Patchset follows. Patchset tested on a smp box with a piix controller.
