gred_change_vq() is called under sch_tree_lock(sch). This means a spinlock is held, and we are not allowed to sleep in this context. We might pre-allocate memory using GFP_KERNEL before taking spinlock, but this is not suitable for stable material. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
