From 1918e341383ab787d6c5b17200f4ed901b10c777 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Wed, 18 Jan 2006 17:43:16 -0800 Subject: [PATCH] [PATCH] svcrpc: save and restore the daddr field when request deferred The server code currently keeps track of the destination address on every request so that it can reply using the same address. However we forget to do that in the case of a deferred request. Remedy this oversight. >From folks at PolyServe. Signed-off-by: J.
