Subject: [AF_UNIX] Initialise UNIX sockets before general device initcalls
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3d36696024499aef19dbf24a781e91a24fbbe4af;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[AF_UNIX] Initialise UNIX sockets before general device initcalls

When drivers call request_module(), it tries to do something with UNIX
sockets and triggers a 'runaway loop modprobe net-pf-1' warning. Avoid
this by initialising AF_UNIX support earlier.
