From 788e69e548cc8d127b90f0de1f7b7e983d1d587a Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Mon, 29 Mar 2010 21:02:31 -0400 Subject: [PATCH] svcrpc: don't hold sv_lock over svc_xprt_put() svc_xprt_put() can call tcp_close(), which can sleep, so we shouldn't be holding this lock. In fact, only the xpt_list removal and the sv_tmpcnt decrement should need the sv_lock here. Reported-by: Mi Jinlong Signed-off-by: J.
