Subject: module: use list_for_each_entry_rcu() on find_module_all()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=93437353daeff31bd5b11810daa4d2d509d1a64e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

module: use list_for_each_entry_rcu() on find_module_all()

The module list has been using RCU in a lot of other calls
for a while now, we just overlooked changing this one over to
use RCU.
