From 8aca67f0ae2d8811165c22326825a645cc8e1b48 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 13 Nov 2006 16:23:44 -0500 Subject: SUNRPC: Fix a potential race in rpc_wake_up_task() Use RCU to ensure that we can safely call rpc_finish_wakeup after we've called __rpc_do_wake_up_task. If not, there is a theoretical race, in which the rpc_task finishes executing, and gets freed first.

The patch was generated using the following script: #!/bin/sh # # Replace one string by another in all the kernel sources. # set -e for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do quilt add $file sed -e "1,\$s/$1/$2/g" $file >/tmp/$$ mv /tmp/$$ $file quilt refresh done The script was run like this sh replace kmem_cache_t "struct kmem_cache" Signed-off-by: Christoph Lameter
