Hi,
This patch series improves usb attached scsi support. It reverts two
bogus fixes which just trade one bug for another, then it fixes the
issues properly.
Any use-after-free issues, leading to horrific "BUG kmalloc-192 (Not
tainted): Poison overwritten" messages and sometimes kernel panics are
gone.
The last patch adds task management support and winds it up in the scsi
error handling callbacks.
Could test it only in non-streams mode, so some additional testing with
usb3 gear would be great. Reviews are very welcome too.
cheers,
Gerd
