From 08d55d7cf3f33c730ce2694393efe16b7983a9c8 Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 4 Dec 2024 07:47:00 +0000 Subject: rxrpc: Don't allocate a txbuf for an ACK transmission Don't allocate an rxrpc_txbuf struct for an ACK transmission. There's now no need as the memory to hold the ACK content is allocated with a page frag allocator. The allocation and freeing of a txbuf is just unnecessary overhead.
