  "message": "mm/pm: force GFP_NOIO during suspend/hibernation and resume\n\nThere are quite a few GFP_KERNEL memory allocations made during\nsuspend/hibernation and resume that may cause the system to hang, because\nthe I/O operations they depend on cannot be completed due to the\nunderlying devices being suspended.\n\nAvoid this problem by clearing the __GFP_IO and __GFP_FS bits in\ngfp_allowed_mask before suspend/hibernation and restoring the original\nvalues of these bits in gfp_allowed_mask durig the subsequent resume.\n\n[akpm@linux-foundation.org: fix CONFIG_PM\u003dn linkage]\nSigned-off-by: Rafael J.
