Nobody cares about libata git trees. If you want some initial test
coverage put it in -mm.

Hi,
I stumbled over a bug in the sata_nv swncq code of the current
2.6.23-git kernel. ata_port_info.flags is always initialised with the
ATA_FLAG_NCQ flag set, but nv_swncq_host_init(...) is only called
if swncq=1 is passed to the driver (default is swncq=0).
I can can

Does anyone have any performance figures to share, with these PMP

Hello,
maybe I should have trusted SiliconImage... But, well, it is not true that
you cannot use PMP with Sil 3512 and 3114. You can, if you try hard enough.
Patch below tries hard enough ;-) Unfortunately it has few drawbacks:

odd that it would be able to be part of an lv's filesystem that had
hundreds of gigabytes recently written to it and then choke on flushing
during shutdown.
And then never comes back.
