The result is faster and simpler code. Patches 1-7 add skb_crc32c() and remove the overly-abstracted and inefficient __skb_checksum(). Patches 8-10 replace skb_copy_and_hash_datagram_iter() with skb_copy_and_crc32c_datagram_iter(), eliminating the unnecessary use of the crypto layer. This unblocks the conversion of nvme-tcp to call crc32c() directly instead of using the crypto layer, which patch 9 does. v1: https://lore.kernel.org/20250511004110.145171-1-ebiggers@kernel.org ==================== Link: https://patch.msgid.link/20250519175012.36581-1-ebiggers@kernel.org Signed-off-by: Jakub Kicinski --- c6634c98e6151ed626a566fbadb54337bb94c532
