The UASP driver saw the follow= ing update: [USB] UASP: Unlock device after reset; EP updates =20 * Unlock the device after reset. =20 * Initialize urb->ep directly. struct uasp_tport_info already records the struct usb_host_endpoint which makes it easy to directly initialize urb->ep. This anticipates when drivers would have to initialize the ep in the urb directly as opposed to the USB core having to use pipes. =20 * Use the UAS pipe macros throughout the code for endpoint indexes. The branch can be found here off of master: https://github.com/ltuikov/linux-2.6 Original posting of the UASP driver can be found here: http://marc.info/?l=3Dlinux-usb&m=3D129165511732388&w=3D2 Luben --- On Thu, 1/13/11, Luben Tuikov wrote: > From: Luben Tuikov > Subject: UASP: updates and merges > To: linux-scsi-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-u= sb-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, "Greg KH" > Date: Thursday, January 13, 2011, 2:45 AM > The UASP driver allows you to connect > to UAS devices and use them > as SCSI devices. >=20 > I've merged latest master (f87813) and resolved a conflict > in drivers/scsi/sd.c by adding back the truncation of the > mode sense data. >=20 > The UASP driver saw the following update: >=20 > =A0 =A0 [USB] UASP: factor out GFP flags and make > them GFP_ATOMIC > =A0 =A0=20 > =A0 =A0 Factor out the GFP flags and make them > atomic: > =A0 =A0 1) The SCSI subsystem uses GFP_ATOMIC, e.g. > before > =A0 =A0 calling the host's slave_alloc callback (at > the > =A0 =A0 time of this commit). > =A0 =A0 2) As we are a storage driver doing I/O, we > should > =A0 =A0 use the lowest denominator (highest > priority) > =A0 =A0 allocation, and of course we shouldn't sleep, > thus > =A0 =A0 use GFP_ATOMIC. >=20 > The branch can be found here (off of master): > https://github.com/ltuikov/linux-2.6 >=20 > Original posting of the UASP driver can be found here: > http://marc.info/?l=3Dlinux-usb&m=3D129165511732388&w=3D2 >=20 > =A0=A0=A0Luben >=20 >=20 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
