From 908c7f1949cb7cc6e92ba8f18f2998e87e265b8e Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 8 Sep 2014 09:51:29 +0900 Subject: percpu_counter: add @gfp to percpu_counter_init() Percpu allocator now supports allocation mask. Add @gfp to percpu_counter_init() so that !GFP_KERNEL allocation masks can be used with percpu_counters too. We could have left percpu_counter_init() alone and added percpu_counter_init_gfp(); however, the number of users isn't that high and introducing _gfp variants to all percpu data structures would be quite ugly, so let's just do the conversion. This is the one with the most users. Other percpu data structures are a lot easier to convert. This patch doesn't make any functional difference.
