Subject: Bugs in usb-skeleton.c??? :)
Date: 13 Jul 2006 15:26:07 +0400 [thread overview]
Message-ID: <m3odvtvj8w.fsf@lx-ltd.ru> (raw)
Hello, All!
As I understand, USB subsystem uses urb->transfer_buffer directly with
DMA. I see that usb-skeleton.c and (at least) bluez's hci_usb allocates it
without GFP_DMA flag. (skeleton with GFP_KERNEL, bluez with GFP_ATOMIC)
(checked versions are 2.4.32 and 2.6.17, ohci only)
Please advise.
