NAK, not-a-bug. The caller actually holds rtnl, it goes through the netdev core ioctl dispatcher: (unregister_netdevice+0x0/0x24) from (fr_ioctl+0x688/0x75c) /* fr_del_pvc() and fr_add_pvc() optimized out by gcc */ (fr_ioctl+0x0/0x75c) from (hdlc_ioctl+0x4c/0x8c) (hdlc_ioctl+0x0/0x8c) from (hss_ioctl+0x3c/0x324) (hss_ioctl+0x0/0x324) from (dev_ifsioc+0x428/0x4e8) (dev_ifsioc+0x0/0x4e8) from (dev_ioctl+0x5d8/0x664) (dev_ioctl+0x0/0x664) from (sock_ioctl+0x90/0x254) (sock_ioctl+0x0/0x254) from (do_ioctl+0x34/0x78) (do_ioctl+0x0/0x78) from (vfs_ioctl+0x78/0x2a8) (vfs_ioctl+0x0/0x2a8) from (sys_ioctl+0x40/0x64) (sys_ioctl+0x0/0x64) from (ret_fast_syscall+0x0/0x2c) The patch would make it deadlock. Please note that sister fr_add_pvc() uses register_netdevice(). The same applies to fr_destroy(). -- Krzysztof Halasa -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
