Subject[PATCHSET percpu/for-3.18] add @gfp to init functions of percpu data structures
Date
There's now a pending patchset[1] which implements atomic percpu
allocation. This patchset propagates @gfp to percpu data structures
so that they can be allocated and initialized from !GFP_KERNEL
contexts too. This will be used for opportunistic allocations of data
structures embedding percpu constructs in IO path.

This patchset adds @gfp to alloc/init functions of percpu_counter,
[flex_]proportions and percpu-refcount. We could add separate
alloc/init functions which take @gfp but there aren't too many users
yet, so let's just add it to the existing ones.

This patchset contains the following patches

0001-percpu_counter-add-gfp-to-percpu_counter_init.patch
0002-proportions-add-gfp-to-init-functions.patch
0003-percpu-refcount-add-gfp-to-percpu_ref_init.patch

and is on top of

[1] [PATCHSET REPOST percpu/for-3.18] percpu: implement atomic allocation support

and avaliable in the following git branch.
