From 6fc166d62c6f9f6eda5ea300f671d34e89bdd3c8 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 9 Mar 2017 08:10:32 +0000 Subject: rxrpc: rxrpc_kernel_send_data() needs to handle failed call better If rxrpc_kernel_send_data() is asked to send data through a call that has already failed (due to a remote abort, received protocol error or network error), then return the associated error code saved in the call rather than ESHUTDOWN. This allows the caller to work out whether to ask for the abort code or not based on this. Signed-off-by: David Howells Signed-off-by: David S.
