Subject: [PATCH] net: tipc: bcast: Replace GFP_ATOMIC with GFP_KERNEL in tipc_bcast_init()
Date: Fri, 27 Jul 2018 17:31:35 +0800 [thread overview]
Message-ID: <20180727093135.7469-1-baijiaju1990@gmail.com> (raw)
tipc_bcast_init() is never called in atomic context.
It calls kzalloc() with GFP_ATOMIC, which is not necessary.
GFP_ATOMIC can be replaced with GFP_KERNEL.
This is found by a static analysis tool named DCNS written by myself.
