Subject: libceph: drop len argument of *verify_authorizer_reply()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0dde584882ade13dc9708d611fbf69b0ae8a9e48;p=linux-beck.git

libceph: drop len argument of *verify_authorizer_reply()

The length of the reply is protocol-dependent - for cephx it's
ceph_x_authorize_reply.  Nothing sensible can be passed from the
messenger layer anyway.
