v2 cover mm/gup, drm/i915: refactor gup_fast, convert to pin_user_pages()

The purpose of posting this series is to launch a test in the intel-gfx-ci tree. (The patches have already been merged into Andrew's linux-mm tree.)

This applies to today's linux.git (note the base-commit tag at the bottom).

Changes since V1:

* Fixed a bug in the refactoring patch: added FOLL_FAST_ONLY to the list of gup_flags *not* to WARN() on. This lead to a failure in the first intel-gfx-ci test run [1].

[1] https://lore.kernel.org/r/[email protected]

Original cover letter:

This needs to go through Andrew's -mm tree, due to adding a new gup.c routine. However, I would really love to have some testing from the drm/i915 folks, because I haven't been able to run-time test that part of it.

Otherwise, though, the series has passed my basic run time testing:
some LTP tests, some xfs and etx4 non-destructive xfstests, and an assortment of other smaller ones: vm selftests, io_uring_register, a few more. But that's only on one particular machine. Also, cross-compile tests for half a dozen arches all pass.

Details:

In order to convert the drm/i915 driver from get_user_pages() to pin_user_pages(), a FOLL_PIN equivalent of __get_user_pages_fast() was required. That led to refactoring __get_user_pages_fast(), with the following goals:

1) As above: provide a pin_user_pages*() routine for drm/i915 to call, in place of __get_user_pages_fast(),

2) Get rid of the gup.c duplicate code for walking page tables with interrupts disabled. This duplicate code is a minor maintenance problem anyway.

3) Make it easy for an upcoming patch from Souptick, which aims to convert __get_user_pages_fast() to use a gup_flags argument, instead of a bool writeable arg. Also, if this series looks good, we can ask Souptick to change the name as well, to whatever the consensus is. My initial recommendation is: get_user_pages_fast_only(), to match the new pin_user_pages_only().

PATCH v2 1/4 mm/gup: move __get_user_pages_fast() down a few lines in gup.c

This is in order to avoid a forward declaration of internal_get_user_pages_fast(), in the next patch.

This is code movement only--all generated code should be identical.

PATCH v2 2/4 mm/gup: refactor and de-duplicate gup_fast() code

In reply to John Hubbard

There were two nearly identical sets of code for gup_fast() style of walking the page tables with interrupts disabled. This has lead to the usual maintenance problems that arise from having duplicated code.

There is already a core internal routine in gup.c for gup_fast(), so just enhance it very slightly: allow skipping the fall-back to "slow" (regular) get_user_pages(), via the new FOLL_FAST_ONLY flag. Then, just call internal_get_user_pages_fast() from __get_user_pages_fast(), and adjust the API to match pre-existing API behavior.

There is a change in behavior from this refactoring: the nested form of interrupt disabling is used in all gup_fast() variants now. That's because there is only one place that interrupt disabling for page walking is done, and so the safer form is required. This should, if anything, eliminate possible (rare) bugs, because the non-nested form of enabling interrupts was fragile at best.

PATCH v2 3/4 mm/gup: introduce pin_user_pages_fast_only()

In reply to John Hubbard

This is the FOLL_PIN equivalent of __get_user_pages_fast(), except with a more descriptive name, and gup_flags instead of a boolean "write" in the argument list.

PATCH v2 4/4 drm/i915: convert get_user_pages() --> pin_user_pages()

In reply to John Hubbard

This code was using get_user_pages*(), in a "Case 2" scenario (DMA/RDMA), using the categorization from [1]. That means that it's time to convert the get_user_pages*() + put_page() calls to pin_user_pages*() + unpin_user_pages() calls.

There is some helpful background in [2]: basically, this is a small part of fixing a long-standing disconnect between pinning pages, and file systems' use of those pages.

I do think it's worth following up on. And it seems like it would be very easy to repro: just hack in a forced failure at the call site of pin_user_pages_fast_only(), and follow the breadcrumbs.

Thanks for the review! And if lifting that check up higher in the call stack is desired, I'm all in favor of that being done...in a separate patch. :)

I'm trying to keep a very light touch when converting these call sites.
