Subject: uas: Fix high-order alloc
|
||||
Origin: http://thread.gmane.org/gmane.linux.usb.general/138042/focus=111495
|
||||
|
||||
Can you try building a kernel with the following line in drivers/usb/storage/uas.c :
|
||||
|
||||
.can_queue = 65536, /* Is there a limit on the _host_ ? */
|
||||
|
||||
(around line 815) Replaced with
|
||||
|
||||
.can_queue = MAX_CMNDS,
|
||||
|
||||
That should help as MAX_CMNDS is 256, so claiming that we can queue more
|
||||
is not helpful, and that likely is what is causing this quite high order alloc.
