From 104b4e5139fe384431ac11c3b8a6cf4a529edf4a Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Tue, 20 Jun 2017 21:01:20 +0300 Subject: percpu_counter: Rename __percpu_counter_add to percpu_counter_add_batch Currently, percpu_counter_add is a wrapper around __percpu_counter_add which is preempt safe due to explicit calls to preempt_disable. Given how __ prefix is used in percpu related interfaces, the naming unfortunately creates the false sense that __percpu_counter_add is less safe than percpu_counter_add. In terms of context-safety, they're equivalent. The only difference is that the __ version takes a batch parameter. Make this a bit more explicit by just renaming __percpu_counter_add to percpu_counter_add_batch. This patch doesn't cause any functional changes. tj: Minor updates to patch description for clarity.
