Error string and comment say we fall back to a default, but in reality we bailed out. Refactor the code to use the core helper which then matches the described behaviour. While updating the init message anyhow, shorten it while we are here; no need for versioning there as well and the name is already given via pr_fmt.

I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR) and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements. Either the device is enumerated and the driver already has a module alias (e.g. PCI, USB etc.) that will get the right driver loaded automatically. Or the device is not enumerated and loading its driver will lead to more or less intrusive hardware poking. Such hardware poking should be limited to a bare minimum, so the user should really decide which drivers should be tried and in what order. Trying them all in arbitrary order can't do any good. On top of that, loading that many drivers at once bloats the kernel log. Also many drivers will stay loaded afterward, bloating the output of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets loaded as a dependency) can't even be unloaded! If defining char-major-10-130 is needed then it should happen in user-space.

This is needed for determining the reason for failure when a softdog timeout occurs. We use softdog to watch for critical application failures and at the minimum a snapshot of the system would help to determine the cause. In such a scenario the application could fail but there isn't a softlockup as such, hence the detect softlockup feature does not help. The patch adds a module parameter soft_panic which when set to 1 causes softdog to invoke panic instead of reboot when the softdog timer expires. By invoking panic we execute kdump if it is configured and the vmcore generated by kdump should provide atleast a minimal idea of the reason for failure.

This brings the watchdog drivers into line with coding style. This patch takes cares of the indentation as described in chapter 1. Main changes: * Re-structure the ioctl switch call for all drivers as follows: switch (cmd) { case WDIOC_GETSUPPORT: case WDIOC_GETSTATUS: case WDIOC_GETBOOTSTATUS: case WDIOC_GETTEMP: case WDIOC_SETOPTIONS: case WDIOC_KEEPALIVE: case WDIOC_SETTIMEOUT: case WDIOC_GETTIMEOUT: case WDIOC_GETTIMELEFT: default: } This to make the migration from the drivers to the uniform watchdog device driver easier in the future.

由 Tim Schmielau 提交于
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

The softdog watchdog timer has a bug that can create an oops: 1. Load the module without the nowayout option. 2. Open the driver and close it without writing 'V' before close. 3. Unload the module. The timer will continue to run... 4. Oops happens when timer fires. Reported Sun, 10 Oct 2004, by Michael Schierl <schierlm@gmx.de> Fix is easy: always take a reference on the module on open. Release it only when the device is closed and no timer is running. Tested on 2.6.13-rc6 using the soft_noboot option. While the timer is running and the device is closed, the module use count stays at 1. After the timer fires, it drops to 0. Repeatedly opening and closing the driver caused no problems. Please apply.

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!
