X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bae65be896cc420f58460cb6f6ac03e71d1bf240;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git nf_conntrack_core: Stop using NLA_PUT*(). These macros contain a hidden goto, and are thus extremely error prone and make code hard to audit. Signed-off-by: David S.
