Streams do not work reliabe on Fresco Logic FL1000G xhci controllers,
trying to use them results in errors like this:

This is yet another Seagate device which needs the US_FL_NO_ATA_1X quirk

This patch set retrieves the number of LUs available on a target
using the report-luns command by re-sizing the returned data
buffer and retrying report luns.
A minor bug fix is included.
scsi_mod parameter max_report_luns is no longer used and is removed.

Update scsi_report_lun_scan to initially always report up to 511 LUs,
as the previous default max_report_luns did. Retry in a loop if not
enough memory is available for the number of LUs reported. Parameter
max_report_luns is removed as it is no longer used.

In support of a /dev/disk/by-slot populated with data from the enclosure and
ses modules udev needs notification when the new interface files/links are
available. Otherwise, any udev rules specified for the disk cannot assume that
the enclosure topology has settled.

Export the NAA logical id for the enclosure. This is optionally available from

These patches include a few enhancements to ses module:

When ring buffer returns an error indicating retry, storvsc may not return a
proper error code to SCSI when bounce buffer is not used. This has introduced
I/O freeze on RAID running atop storvsc devices. This patch fixes it by always
returning a proper error code.
