To which software revision would you like to refer here?

How does the presented information fit to a statement like the following?
https://elixir.bootlin.com/linux/v6.12-rc6/source/drivers/net/ethernet/chelsio/inline_crypto/ch_ktls/chcr_ktls.c#L442

	if (u_ctx && u_ctx->detach)
		goto out;


Would you eventually like to trace the control flow back any further
for the data structure member “handle”?
