Subject: [PATCH net-next v2 0/2] Avoid explicit cpumask var allocation on stack
Date: Sun, 31 Mar 2024 13:34:39 +0800 [thread overview]
Message-ID: <20240331053441.1276826-1-dawei.li@shingroup.cn> (raw)
Hi,
This is v2 of previous series[1] about cpumask var on stack for net
subsystem.
Change since v1:
- For iucv_setmask_up() which returns void to caller, just make cpumask
var static which is protected by global lock iucv_register_mutex. [Eric]
[1] v1:

Hi,
This is v2 of previous series[1] about cpumask var on stack for net
subsystem.
Change since v1:
- For iucv_setmask_up() which returns void to caller, just make cpumask
var static which is protected by global lock iucv_register_mutex. [Eric]
[1] v1:
