Subject: [PATCH] kbuild: revert "fix make -jN with multiple targets with O=..."
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=36cbbe5eb9857730768aa5f54ad94d69e0b2133d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] kbuild: revert "fix make -jN with multiple targets with O=..."

Commit 296e0855b0f9a4ec9be17106ac541745a55b2ce1:

    "kbuild: fix make -jN with multiple targets with O=..."

causes a ~95% increase in build time for the kernel.  Before: 4m21s
after: 8m1.403s.  Can we revert this until another approach is found?
