From: Mike Christie <michael.christie@oracle.com> stable inclusion from linux-4.19.143 commit 2229e50f25a5d9e6fa9aa263530978a8c83ff944 -------------------------------- [ Upstream commit fa39ab5184d64563cd36f2fb5f0d3fbad83a432c ] ixgbe_fcoe_ddp_setup() can be called from the main I/O path and is called with a spin_lock held, so we have to use GFP_ATOMIC allocation instead of GFP_KERNEL.
