Hugh Dickins 1cbf0a5884 ext4: add __GFP_NOWARN to GFP_NOWAIT in readahead 
Since commit e509ad4d77e6 ("ext4: use bdev_getblk() to avoid memory
reclaim in readahead path") rightly replaced GFP_NOFAIL allocations by
GFP_NOWAIT allocations, I've occasionally been seeing "page allocation
failure: order:0" warnings under load: all with
ext4_sb_breadahead_unmovable() in the stack.  I don't think those warnings
are of any interest: suppress them with __GFP_NOWARN.
