Hi everyone,
This is ver.5 patchset for fixing hugepage migration's race problem.
In ver.4, Hugh enlighted me about the problem around pmd_huge(), where
pmd_huge() returned false for migration/hwpoison entry and we treated them
as normal pages. IOW, we didn't handle !pmd_present case properly.
non_swap_entry() returns true if a given swp_entry_t is a migration
entry or hwpoisoned entry. So non_swap_entry() is_migration_entry() is
identical with just is_migration_entry(). So by removing non_swap_entry(),
we can write is_hugetlb_entry_(migration|hwpoisoned)() more simply.
And the name
There is a race condition between hugepage migration and change_protection(),
where hugetlb_change_protection() doesn't care about migration entries and
wrongly overwrites them. That causes unexpected results like kernel crash.
HWPoison entries also can cause the same problem.
This patch adds
Migrating hugepages and hwpoisoned hugepages are considered as
non-present hugepages, and they are referenced via migration entries
and hwpoison entries in their page table slots.
This behavior causes race condition because pmd_huge() doesn't tell
non-huge pages from migrating/hwpoisoned
Currently hugetlb_fault() checks at first whether pte of the faulted address
is a migration or hwpoisoned entry, which means that we call huge_ptep_get()
twice in single hugetlb_fault(). This is not optimized. The reason of this
approach is that without checking at first, huge_pte_alloc() can

If __unmap_hugepage_range() tries to unmap the address range over which

Currently we have many duplicates in definitions around follow_huge_addr(),

The basic idea is to put the default implementation for these functions in

We have a race condition between move_pages() and freeing hugepages,
where move_pages() calls follow_page(FOLL_GET) for hugepages internally

When running the test which causes the race as shown in the previous patch,

Whether there is a vm_ops-page_mkwrite or not, the page dirtying is
pretty much the same. Make sure the page references are the same in
both cases, then merge the two branches.
It's tempting to go even further and page-lock the !page_mkwrite

oom_kill.c assumes that PF_EXITING task should exit and free the memory

clarification of _shipped files intent
The rational for using _shipped files should be clearly
indicated so that it does not look like it is encouraging
binary blobs.
This patch is against linux 3.18.0-rc6
Note that the original file uses leading tabs so for this
patch this was retained.
This patchset cleanup includes documentation updates for _shipped files,
offset header files as well as some directly related change proposals
in Kbuild and CodingStyle.
This proposed patch set describes the intent and use of _shipped files
and offset header files as well as a minor update on
limit _shipped to c h and S files
_shipped targets are intended for generated source files which should
not permit .o binary blobs which is currently the case. This patch
simply restricts _shipped targets to .c, .h and .S files.
A special case for .inc_shipped is added to prevent breaking

Currently shipped files have more or less free style indications
of how to generate them respectively what the sources are, in

for automated checking.
