Merge tag 'for-usb-next-2014-03-06' of git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-next
Sarah writes: xhci: Streams and UAS cleanups, misc cleanups for 3.15 Hi Greg, Here's 76 patches to queue to usb-next for 3.15. The bulk of this rather large pull request is the UAS driver cleanup, the xHCI streams fixes, and the new userspace API for usbfs to be able to use and alloc/free bulk streams. I've hammered on these changes, and the UAS driver seems solid. The performance numbers are pretty spiffy too: root@xanatos:~# echo 3 > /proc/sys/vm/drop_caches; dd if=/dev/sdb of=/dev/null bs=4k count=1000M iflag=count_bytes 256000+0 records in 256000+0 records out 1048576000 bytes (1.0 GB) copied, 3.28557 s, 319 MB/s That's about 100 MB/s faster than my fastest Bulk-only-Transport mass storage drive. There's a couple of miscellaneous cleanup patches and non-urgent bug fixes in here as well: 7969943789df xhci: add the meaningful IRQ description if it is empty bcffae7708eb xhci: Prevent runtime pm from autosuspending during initialization e587b8b270d3 xhci: make warnings greppable 25cd2882e2fc usb/xhci: Change how we indicate a host supports Link PM.
