rmmod/3080 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire: (proc_subdir_lock){--..}, at: [<c04a33b0>] remove_proc_entry+0x40/0x191 and this task is already holding: (ide_lock){++..}, at: [<c05651a2>] ide_unregister_subdriver+0x39/0xc8 which would create a new lock dependency: (ide_lock){++..} -> (proc_subdir_lock){--..} but this new dependency connects a hard-irq-safe lock: (ide_lock){++..} ... which became hard-irq-safe at: [<c043c458>] lock_acquire+0x4b/0x6b [<c06129d7>] _spin_lock_irqsave+0x22/0x32 [<c0567870>] ide_intr+0x17/0x1a9 [<c044eb31>] handle_IRQ_event+0x20/0x4d [<c044ebf2>] __do_IRQ+0x94/0xef [<c0406771>] do_IRQ+0x9e/0xbd to a hard-irq-unsafe lock: (proc_subdir_lock){--..} ... which became hard-irq-unsafe at: ...

In specific, the call to ide_add_proc_entries() is unprotected, and there is nothing else in the file using the respective ->proc fields. Also the lock order around destroy_proc_ide_interface() suggests this. Alan sayeth: proc_ide_write_settings walks the setting list under ide_setting_sem, read ditto. remove_proc_entry is doing proc side housekeeping. Looks fine to me, although that old code is such a mess anything could be going on.

Michal Miroslaw reported a problem (bugzilla #7023) where a user initiated reset while the IDE layer was already resetting the channel caused a crash, and provided a rough fix. This is a slightly cleaner version of the fix which tracks the reset state and blocks further reset requests while a reset is in progress. Note this is not a security issue - random end users can't access the ioctl in question anyway.

This patch stops CompactFlash devices being marked as removable. They are not removable (as defined by Linux) as the media and device are inseparable. When a card is removed, the whole device is removed from the system and never sits in a media-less state. This stops some nasty udev device creation/destruction loops. Further, once this change is made, there is no need for ide to can be removed from ide_drive_t.

HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

IDE: MODALIAS support for autoloading of ide-cd, ide-disk, ... Add MODULE_ALIAS to IDE midlayer modules: ide-disk, ide-cd, ide-floppy and ide-tape, to autoload these modules depending on the probed media type of the IDE device. It is used by udev and replaces the former agent shell script of the hotplug package, which was required to lookup the media type in the proc filesystem. Using proc was racy, cause the media file is created after the hotplug event is sent out. The module autoloading does not take any effect, until something like the following udev rule is configured: SUBSYSTEM=="ide", ACTION=="add", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe $env{MODALIAS}" The module ide-scsi will not be autoloaded, cause it requires manual configuration. It can't be, and never was supported for automatic setup in the hotplug package. Adding a MODULE_ALIAS to ide-scsi for all supported media types, would just lead to a default blacklist entry anyway. $ modinfo ide-disk filename: /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko description: ATA DISK Driver alias: ide:*m-disk* license: GPL ... $ modprobe -vn ide:m-disk insmod /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko $ cat /sys/bus/ide/devices/0.0/modalias ide:m-disk It also adds attributes to the IDE device: $ tree /sys/bus/ide/devices/0.0/ /sys/bus/ide/devices/0.0/ |-- bus -> ../../../../../../../bus/ide |-- drivename |-- media |-- modalias |-- power | |-- state | `-- wakeup `-- uevent $ cat /sys/bus/ide/devices/0.0/{modalias,drivename,media} ide:m-disk hda disk Signed-off-by: NKay Sievers <kay.sievers@suse.de> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
