由 Jonathan Brassow 提交于
A clear_region function is permitted to block (in practice, rare) but gets called in rh_update_states() with a spinlock held. The bits being marked and cleared by the above functions are used to update the on-disk log, but are never read directly. We can perform these operations outside the spinlock since the bits are only changed within one thread viz. - mark_region in rh_inc() - clear_region in rh_update_states(). So, we grab the clean_regions list items via list_splice() within the spinlock and defer clear_region() until we iterate over the list for deletion - similar to how the recovered_regions list is already handled. We then move the flush() call down to ensure it encapsulates the changes which are done by the later calls to clear_region().

Allow invalid snapshots to be activated instead of failing.

Process persistent exception store metadata IOs in a separate thread. A snapshot may become invalid while inside generic_make_request(). A synchronous write is then needed to update the metadata while still inside that function. Since the introduction of md-dm-reduce-stack-usage-with-stacked-block-devices.patch this has to be performed by a separate thread to avoid deadlock.

Video mode probing for the new x86 setup code. This code breaks down different drivers into modules. This code deliberately drops support for a lot of the vendor-specific mode probing present in the assembly version, since a lot of those probes have been found to be stale in current versions of those chips -- frequently, support for those modes have been dropped from recent video BIOSes due to space constraints, but the video BIOS signatures are still the same.
