The current check for 'backward merging' within add_active_range() does not seem correct. start_pfn must be compared against early_node_map[i].start_pfn (and NOT against .end_pfn) to find out whether the new region is backward-mergeable with the existing range.

Right now for kfifo_*_user it's not easily possible to distingush between a user copy failing and the FIFO not containing enough data. The problem is that both conditions are multiplexed into the same return code. Avoid this by moving the "copy length" into a separate output parameter and only return 0/-EFAULT in the main return value. I didn't fully adapt the weird "record" variants, those seem to be unused anyways and were rather messy (should they be just removed?) I would appreciate some double checking if I did all the conversions correctly.

The m68knommu coldfire pit clocksource looks like it was incorrectly marked as a continuous clocksource. Running with it marked as a continuous clocksource could cause hangs when the system switches to highres mode or enables nohz. This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit clocksource. This will disallow systems using this clocksource from entering oneshot mode (disabling highres timers and nohz).

由 Eric Paris 提交于
Since commit 7e790dd5 ("inotify: fix error paths in inotify_update_watch") inotify changed the manor in which it gave watch descriptors back to userspace. Previous to this commit inotify acted like the following: inotify_add_watch(X, Y, Z) = 1 inotify_rm_watch(X, 1); inotify_add_watch(X, Y, Z) = 2 but after this patch inotify would return watch descriptors like so: inotify_add_watch(X, Y, Z) = 1 inotify_rm_watch(X, 1); inotify_add_watch(X, Y, Z) = 1 which I saw as equivalent to opening an fd where open(file) = 1; close(1); open(file) = 1; seemed perfectly reasonable. The issue is that quite a bit of userspace apparently relies on the behavior in which watch descriptors will not be quickly reused. KDE relies on it, I know some selinux packages rely on it, and I have heard complaints from other random sources such as debian bug 558981. Although the man page implies what we do is ok, we broke userspace so this patch almost reverts us to the old behavior. It is still slightly racey and I have patches that would fix that, but they are rather large and this will fix it for all real world cases. The race is as follows: - task1 creates a watch and blocks in idr_new_watch() before it updates the hint. - task2 creates a watch and updates the hint. - task1 updates the hint with it's older wd - task removes the watch created by task2 - task adds a new watch and will reuse the wd originally given to task2 it requires moving some locking around the hint (last_wd) but this should solve it for the real world and be -stable safe. As a side effect this patch papers over a bug in the lib/idr code which is causing a large number WARN's to pop on people's system and many reports in kerneloops.org. I'm working on the root cause of that idr bug seperately but this should make inotify immune to that issue.

Many platform support this feature, and it can provide significant power savings when the reduced refresh rate is low. However, on some platforms a secondary (reduced) timing is provided but not actually supported by the hardware. This results in undesirable flicker at runtime. So disable the feature by default, but allow users to opt-in to the reduced clock behavior with a new module parameter, lvds_downclock, that can be set to 1 to enable the feature.
