[PATCH 1/3] tree wide: get rid of __GFP_REPEAT for order-0 allocations part I
From: mhocko
Date: Thu Nov 05 2015 - 11:16:25 EST
From: Michal Hocko <mhocko@xxxxxxxx>
__GFP_REPEAT has a rather weak semantic but since it has been introduced
around 2.6.12 it has been ignored for low order allocations. Yet we have
the full kernel tree with its usage for apparently order-0 allocations.
This is really confusing because __GFP_REPEAT is explicitly documented
to allow allocation failures which is a weaker semantic than the current
order-0 has (basically nofail).
Let's simply reap out __GFP_REPEAT from those places. This would allow
to identify place which really need allocator to retry harder and
formulate a more specific semantic for what the flag is supposed to do
actually.
