The patch titled
Subject: memcg: replace __always_inline with plain inline
has been removed from the -mm tree. Its filename was
memcg-kmem-controller-infrastructure-replace-__always_inline-with-plain-inline.patch
This patch was dropped because it was folded into memcg-kmem-controller-infrastructure.patch
------------------------------------------------------
From: Glauber Costa <glommer@xxxxxxxxxxxxx>
Subject: memcg: replace __always_inline with plain inline
Following the pattern found in the allocators, where we do our best to the
fast paths function-call free, all the externally visible functions for
kmemcg were marked __always_inline.
It is fair to say, however, that this should be up to the compiler. We
will still keep as much of the flag testing as we can in memcontrol.h to
give the compiler the option to inline it, but won't force it.
I tested this with 4.7.2, it will inline all three functions anyway when
compiling with -O2, and will refrain from it when compiling with -Os.
This seems like a good behavior.
