2010-02-17CAPI: Rework controller state notifierJan Kiszka
Another step towards proper locking: Rework the callback provided to capidrv for controller state changes. This is so far attached to an application, which would require us to hold the corresponding lock across notification calls. But there is no direct relation between a controller up/down event and an application, so let's decouple them and provide a notifier call chain for those events instead. This notifier chain is first of all used internally. Here we request the highest priority to unsure that housekeeping work is done before any other notifications. The chain is exported via [un]register_capictr_notifier to our only user, capidrv, to replace the racy and unfixable capi20_set_callback.

2008-04-19include: Remove unnecessary inclusions of asm/semaphore.hMatthew Wilcox
None of these files use any of the functionality promised by asm/semaphore.h. It's possible that they (or some user of them) rely on it dragging in some unrelated header file, but I can't build all these files, so we'll have to fix any build failures as they come up.

2007-07-17Use mutex instead of semaphore in CAPI 2.0 driverMatthias Kaehlcke
The CAPI 2.0 driver uses a semaphore as mutex. Use the mutex API instead of the (binary) semaphore.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
