commit 6022ccd4cab89944ca390c23de13cdc54cf05b1f
Author: Mark Wielaard <mjw@redhat.com>
Date:   Mon Oct 31 10:39:10 2011 +0100

    Introduce and use STP_ALLOC_SLEEP_FLAGS for use with gfp alloc functions.
    
    When in a context where we can wait we like to use normal GFP_KERNEL.
    But this might trigger the oom-killer, which might kill out own stapio
    process. To suppress this use __GFP_NORETRY. All _stp_[kmz]alloc_gfp
    functions that are used in user context should use STP_ALLOC_SLEEP_FLAGS
    if appropriate.
    
    Note that the kernel itself may still use GFP_KERNEL. For example
    __alloc_percpu() will always use GFP_KERNEL.
