To address this, it is better to add a sendpage_ok() check\nwithin the driver itself, and if it returns 0, then MSG_SPLICE_PAGES flag\nshould be disabled before entering the network stack.\n\nA similar issue has been discussed for NVMe in this thread:\nhttps://lore.kernel.org/all/20240530142417.146696-1-ofir.gal@volumez.com/\n\n  WARNING: CPU: 0 PID: 5342 at net/core/skbuff.c:7140 skb_splice_from_iter+0x173/0x320\n  Call Trace:\n   tcp_sendmsg_locked+0x368/0xe40\n   siw_tx_hdt+0x695/0xa40 [siw]\n   siw_qp_sq_process+0x102/0xb00 [siw]\n   siw_sq_resume+0x39/0x110 [siw]\n   siw_run_sq+0x74/0x160 [siw]\n   kthread+0xd2/0x100\n   ret_from_fork+0x34/0x40\n   ret_from_fork_asm+0x1a/0x30"

Para solucionar esto, es mejor agregar una comprobaci\u00f3n sendpage_ok() dentro del propio controlador y, si devuelve 0, entonces se debe deshabilitar el indicador MSG_SPLICE_PAGES antes de ingresar a la pila de red.
