Subject: [PATCH 6.7 239/641] rxrpc: Fix skbuff cleanup of calls recvmsg_queue and rx_oos_queue
6.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Howells <dhowells@...hat.com>
[ Upstream commit 4fc68c4c1a114ba597b4f3b082f04622dfa0e0f6 ]
Fix rxrpc_cleanup_ring() to use rxrpc_purge_queue() rather than
skb_queue_purge() so that the count of outstanding skbuffs is correctly
updated when a failed call is cleaned up.
Without this rmmod may hang waiting for rxrpc_n_rx_skbs to become zero.
Fixes: 5d7edbc9231e ("rxrpc: Get rid of the Rx ring")
