net: Fix module refcount leak in kernel_accept()
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().
