Subject: Dont touch fs_struct in usermodehelper
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=db74ece990ea59a9ec9f00f8881026059ef5caf5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Dont touch fs_struct in usermodehelper

This test seems to be unnecessary since we always have rootfs mounted before
calling a usermodehelper.
