Subject: netfilter: nf_tables: pass set description to ->privsize
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=347b408d59e7eadcd09f97eba96fa4c270eb3b23;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

netfilter: nf_tables: pass set description to ->privsize

The new non-resizable hashtable variant needs this to calculate the
size of the bucket array.
