[PATCH] afs: Fix possible assert with callbacks from yfs servers

From: David Howells
Date: Thu Nov 21 2019 - 10:26:27 EST


From: Marc Dionne <marc.dionne@xxxxxxxxxxxx>

Servers sending callback breaks to the YFS_CM_SERVICE service may
send up to YFSCBMAX (1024) fids in a single RPC. Anything over
AFSCBMAX (50) will cause the assert in afs_break_callbacks to trigger.

Remove the assert, as the count has already been checked against
the appropriate max values in afs_deliver_cb_callback and
afs_deliver_yfs_cb_callback.

Fixes: 35dbfba3111a ("afs: Implement the YFS cache manager service")
