ntb: ntb_transport: Replace GFP_ATOMIC with GFP_KERNEL in ntb_transport_setup_qp_mw
ntb_transport_setup_qp_mw() is never called in atomic context. ntb_transport_setup_qp_mw() is only called by ntb_transport_link_work(), which is set as a parameter of INIT_DELAYED_WORK() in ntb_transport_probe(). Despite never getting called from atomic context, ntb_transport_setup_qp_mw() calls kzalloc_node() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
