Miller" <davem@...emloft.net>, "netdev@...r.kernel.org" <netdev@...r.kernel.org>, linux-kernel <linux-kernel@...r.kernel.org>, ldv-project@...uxtesting.org Subject: [BUG] might sleep functions in atomic context in stmmac_resume() There are calls to might sleep functions in atomic context in stmmac_resume(): - the first one is clk_prepare_enable(priv->stmmac_clk); - the second one is stmmac_hw_setup() -> init_dma_desc_rings() -> stmmac_init_rx_buffers() -> __netdev_alloc_skb(GFP_KERNEL) What is the purpose of spin_lock_irqsave(&priv->lock, flags) section? What does it protect against?
