4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Hans de Goede <hdegoede@xxxxxxxxxx> commit 55ff8cfbc4e12a7d2187df523938cc671fbebdd1 upstream. The uas driver can never queue more then MAX_CMNDS (- 1) tags and tags are shared between luns, so there is no need to claim that we can_queue some random large number. Not claiming that we can_queue 65536 commands, fixes the uas driver failing to initialize while allocating the tag map with a "Page allocation failure (order 7)" error on systems which have been running for a while and thus have fragmented memory.
