Tail page refcounting is utterly complicated and painful to support.

We're going to allow mapping of individual 4k pages of THP compound
page. It means we cannot rely on PageTransHuge() check to decide if
map/unmap small page or THP.
The patch adds new argument to rmap functions to indicate whether we want
to operate on whole compound page or only the small page.
We are going to decouple splitting THP PMD from splitting underlying
compound page.
This patch renames split_huge_page_pmd*() functions to split_huge_pmd*()
to reflect the fact that it doesn't imply page splitting, only PMD.

With new refcounting THP can belong to several VMAs. This makes tricky
to track THP pages, when they partially mlocked. It can lead to leaking
mlocked pages to non-VM_LOCKED vmas and other problems.
With this patch we will split all pages on mlock and avoid
fault-in/collapse new THP in VM_LOCKED v
This adds inotify/ to the kselftests suite. It currently only includes a

The current inotify API only provides a single function to add *and*
modify watch descriptors. There is no way to perform either operation
explicitly, but the kernel always automatically chooses what to do. If
the watch-descriptor exists, it is updated, otherwise a new descriptor is
allocated. This
Currently, inotify_update_existing_watch() first looks up the requested
wd before modifying it. This makes the function unsuitable for cases
where we already know the wd. Change the behavior to directly accept wd
as input and make the only caller do the lookup themself.

Hi
The current inotify API suffers from a nasty race-condition if you try to
update watch descriptors (where the update _changes_ flags, not only adds new
flags). The problem is, that an explicit update of a watch-descriptor might
result in updating an unrelated, existing watch descriptor that jus

Thanks for the 'heads-up', I think that the HID++ stuff I have in progress
won't be ready until the 4.4 cycle,
