Subject: ceph: rename prepare_connect_authorizer()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=dac1e716c60161867a47745bca592987ca3a9cb2;p=openwrt%2Fstaging%2Fblogic.git

ceph: rename prepare_connect_authorizer()

Change the name of prepare_connect_authorizer().  The next
patch is going to make this function no longer add anything to the
connection's out_kvec, so it will no longer fit the pattern of
the rest of the prepare_connect_*() functions.

In addition, pass the address of a variable that will hold the
authorization protocol to use.  Move the assignment of that to the
connection's out_connect structure into prepare_write_connect().
