The patch titled
AFS: use patched rxrpc_kernel_send_data() correctly
has been removed from the -mm tree. Its filename was
afs-use-patched-rxrpc_kernel_send_data-correctly.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: AFS: use patched rxrpc_kernel_send_data() correctly
From: David Howells <dhowells@xxxxxxxxxx>
Fix afs_send_simple_reply() to accept a greater-than-zero return value from
rxrpc_kernel_send_data() as being a successful return rather than thinking
it an error and aborting the call.
rxrpc_kernel_send_data() previously returned zero incorrectly when it
worked successfully, but has been patched to return the number of bytes it
transmitted.
