[PATCH 00/11] add recovery entity

[Christian König]

Well that is a clear NAK to this whole approach.

Submitting the recovery jobs to the scheduler is reentrant because the 
scheduler is the one who originally signaled us of a timeout.

Why not submit the recovery jobs to the hardware ring directly?

Regards,
Christian.
