From: Chuck Lever Date: Fri, 22 Aug 2014 19:10:59 +0000 (-0400) Subject: NFSD: Always initialize cl_cb_addr X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b0d2e42cce8fbf12998a24abf62a26c895dd2fd2;p=linux-beck.git NFSD: Always initialize cl_cb_addr A client may not want to use the back channel on a transport it sent CREATE_SESSION on, in which case it clears SESSION4_BACK_CHAN. However, cl_cb_addr should be populated anyway, to be used if the client binds other connections to this session. If cl_cb_addr is not initialized, rpc_create() fails when the server attempts to set up a back channel on such secondary transports. Signed-off-by: Chuck Lever Signed-off-by: J.
