From 1991722a70ffb1f0199a5690a31a5c7822007b1f Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Tue, 14 Jan 2020 11:11:17 -0400 Subject: mm/mmu_notifiers: Use 'subscription' as the variable name for mmu_notifier The 'subscription' is placed on the 'notifier_subscriptions' list. This eliminates the poor name 'mn' for this variable.
