Agree with all above, and what you ask is right what we are doing in the 3rd change - get rid of host lock on dispatch and completion paths. I agree with using dedicated spin locks for dedicated purposes in UFS driver, e.g., clk gating has its own gating_lock and clk scaling has its own scaling_lock. But this specific series is only for improving performance. We will take your comments into consideration and address it in future.
Thanks! Bart. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
