Subject: [NETNS]: Don't memset() netns to zero manually
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=32f0c4cbe495d121c09ed14d9c84f9e1b9574415;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[NETNS]: Don't memset() netns to zero manually

The newly created net namespace is set to 0 with memset()
in setup_net(). The setup_net() is also called for the
init_net_ns(), which is zeroed naturally as a global var.

So remove this memset and allocate new nets with the
kmem_cache_zalloc().
