Subject[PATCH] kernel/rcu/tree.c: fix kernel-doc warnings
Date
From: Randy Dunlap <rdunlap@infradead.org>

Fix kernel-doc warnings:

../kernel/rcu/tree.c:959: warning: Excess function parameter 'irq' description in 'rcu_nmi_enter'
../kernel/rcu/tree.c:3006: warning: Function parameter or member 'count' not described in 'kfree_rcu_cpu'

Fixes: cf7614e13c8f ("rcu: Refactor rcu_{nmi,irq}_{enter,exit}()")
Fixes: 9154244c1ab6 ("rcu/tree: Add a shrinker to prevent OOM due to kfree_rcu() batching")
