At the very end of my startup scripts, I say
pktsetup cdrw /dev/cdrw
to get the stuff in /etc/pktcdvd set up right.
As of 2.6.27 this has started complaining:
pktcdvd: writer pktcdvd0 mapped to hde ------------[ cut here ]------------ WARNING: at fs/sysfs/dir.c:463 sysfs_add_one+0x2f/0x3b() sysfs: duplicate filename '254:0' can not be created Modules linked in: Pid: 1306, comm: pktsetup Not tainted 2.6.27-dirty #1 [<c011ac1c>] warn_slowpath+0x50/0x71 [<c0245c17>] ? ida_get_new_above+0xdc/0x17d [<c0245a8a>] ? idr_get_empty_slot+0x142/0x1f3 [<c0245c17>] ? ida_get_new_above+0xdc/0x17d [<c01a1738>] ? sysfs_ilookup_test+0x0/0x16 [<c01a1919>] ? sysfs_find_dirent+0x1b/0x2c [<c01a1aba>] sysfs_add_one+0x2f/0x3b [<c01a26f6>] sysfs_do_create_link+0xb1/0x106 [<c01a276b>] sysfs_create_link+0xf/0x14 [<c02749d2>] device_add+0x134/0x455 [<c0274d0a>] device_register+0x17/0x1a [<c0274d8d>] device_create_vargs+0x80/0xa3 [<c0274dd0>] device_create+0x20/0x24 [<c028208f>] pkt_setup_dev+0x2ed/0x429 [<c0282251>] pkt_ctl_ioctl+0x86/0x18c [<c0170c09>] vfs_ioctl+0x55/0x6e [<c0185801>] ? block_truncate_page+0xa9/0x1e0 [<c0170e58>] do_vfs_ioctl+0x236/0x249 [<c0170e9c>] sys_ioctl+0x31/0x4d [<c0102c8d>] sysenter_do_call+0x12/0x25 [<c0185801>] ? block_truncate_page+0xa9/0x1e0 ======================= ---[ end trace 1cdd10ab78ee5bc6 ]---
For the life of me I can't see where pkt_sysfs_dev_new() is being called more than once: indeed, from the trace above GCC has inlined it into pkt_setup_dev() as a static function called from only one place...
