commit 9469b9f3491d1a7c6329be6c5dcc2611fdce8b17 Author: Matthew Dillon <dillon@apollo.backplane.com> Date: Wed Aug 19 14:49:14 2009 -0700 NATA - Replace the queuing algorithm with the one used by bioq. * NATA doesn't use bioq yet, but I replicated the algorithm to fix the read starvation issue. * Interesting note: Because NATA does not have NCQ reads appear to be prioritized even more then they are on AHCI.
