Tested: selftests Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2143700 commit 2d91ecace6614cf6254001566292b808d7f70a91 Author: Jakub Kicinski <kuba@kernel.org> Date: Thu Jul 7 18:03:09 2022 -0700 strparser: pad sk_skb_cb to avoid straddling cachelines sk_skb_cb lives within skb->cb[]. skb->cb[] straddles 2 cache lines, each containing 24B of data. The first cache line does not contain much interesting information for users of strparser, so pad things a little. Previously strp_msg->full_len would live in the first cache line and strp_msg->offset in the second. We need to reorder the 8 byte temp_reg with struct tls_msg to prevent a 4B hole which would push the struct over 48B.
