From 0b83ae960cd7d4a5ee02786ecf41ab45688999bf Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Wed, 15 Dec 2010 15:44:06 -0500 Subject: USB: uas: Use GFP_NOIO instead of GFP_KERNEL in I/O submission path If swap is on a UAS device, we could recurse into the driver by using GFP_KERNEL. Using GFP_NOIO ensures we won't.
