![]() The kernel_accept() does not hold the module refcount of newsock->ops->owner, so we need __module_get(newsock->ops->owner) code after call kernel_accept() by hand. In sunrpc, the module refcount is missing to hold. So this cause kernel panic. Used following script to reproduct: while [ 1 ]; do mount -t nfs4 192.168.0.19:/ /mnt touch /mnt/file umount /mnt lsmod | grep ipv6 done This patch fixed the problem by add __module_get(newsock->ops->owner) to kernel_accept(). So we do not need to used __module_get(newsock->ops->owner) in every place when used kernel_accept(). Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: David S.
