Reference-putting functions should not access the object being put after decrementing the refcount unless they reduce the refcount to zero. Fix a couple of instances of this in afs by copying the information to be logged by tracepoint to local variables before doing the decrement. [Fixed a bit in afs_put_server() that I'd missed but Marc caught] Fixes: 341f741f ("afs: Refcount the afs_call struct") Fixes: 45218193 ("afs: Trace afs_server usage") Fixes: 977e5f8e ("afs: Split the usage count on struct afs_server") Signed-off-by: David Howells <dhowells@redhat.com> cc: Marc Dionne <marc.dionne@auristor.com> cc: linux-afs@lists.infradead.org Link: https://lore.kernel.org/r/165911278430.3745403.16526310736054780645.stgit@warthog.procyon.org.uk/ # v1
