From 501d52a90cbe652b41336c206ff0e95799d5a9b5 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Mon, 19 May 2014 08:55:40 -0700 Subject: bcache: Allocate bounce buffers with GFP_NOWAIT There's no point in blocking on these allocations, since our fallback paths will probably go faster than blocking.
