6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Howells <dhowells@xxxxxxxxxx>
[ Upstream commit e30458d690f35abb01de8b3cbc09285deb725d00 ]
Fix a pair of bugs in the fallback handling for the YFS.RemoveFile2 RPC
call:
(1) Fix the abort code check to also look for RXGEN_OPCODE. The lack of
this masks the second bug.
(2) call->server is now not used for ordinary filesystem RPC calls that
have an operation descriptor. Fix to use call->op->server instead.
Fixes: e49c7b2f6de7 ("afs: Build an abstraction around an "operation" concept")
