Moreover, since memory allocations are\ngoing to be used for the hibernation memory shrinking, it will be even\nmore likely to happen during hibernation.\n\nTo prevent it from happening, introduce the oom_killer_disabled switch\nthat will cause __alloc_pages_internal() to fail in the situations in\nwhich the OOM killer would have been called and make the freezer set\nthis switch after tasks have been successfully frozen.\n\n[akpm@linux-foundation.org: be nicer to the namespace]\nSigned-off-by: Rafael J.
