Hi!
Even with fe6a8fc5ed2f0081f17375ae2005718522c392c6 the LOOP_CONFIGURE

lo_offset/lo_sizelimit fields are set to non-zero.

memalloc_use_memcg() worked for kernel allocations but was silently
ignored for user pages.
This patch establishes a precedence order for who gets charged:
1. If there is a memcg associated with the page already, that memcg is
charged. This happens during swapin.

The current code only associates with the existing blkcg when aio is

We can skip most of the initialisation, although spinlocks still
need explicit initialisation as architectures may use a non-zero

We can only kmap() one subpage of a THP at a time, so loop over all

If iomap_unshare_actor() unshares to an inline iomap, the page was
not being flushed. block_write_end() and __iomap_write_end() already
contain flushes, so adding it to iomap_write_end_inline() seems like
the best place. That means we can remove it from iomap_write_actor().

If the page is compound, check the last index in the page and return
the appropriate size. Change the return type to ssize_t in case we ever
support pages larger than 2GB.

These patches are carefully plucked from the THP series. I would like
them to hit 5.10 to make the THP patchset merge easier. Some of these
are just generic improvements that make sense on their own terms, but
the overall intent is to support THPs in iomap.
I'll send another patch series later

iomap_write_end cannot return an error, so switch it to return
size_t instead of int and remove the error checking from the callers.
Also convert the arguments to size_t from unsigned int, in case anyone
ever wants to support a page size larger than 2GB.

Size the uptodate array dynamically to support larger pages in the
page cache. With a 64kB page, we're only saving 8 bytes per page today,
but with a 2MB maximum page size, we'd have to allocate more than 4kB
per page. Add a few debugging assertions.

Pass the full length to iomap_zero() and dax_iomap_zero(), and have
them return how many bytes they actually handled. This is preparatory
work for handling THP, although it looks like DAX could actually take
advantage of it if there's a larger contiguous area.

This helper is useful for both THPs and for supporting block size larger
than page size. Convert all users that I could find (we have a few
different ways of writing this idiom, and I may have missed some).

Instead of counting bio segments, count the number of bytes submitted.
This insulates us from the block layer's definition of what a 'same page'
is, which is not necessarily clear once THPs are involved.

Now that the bitmap is protected by a spinlock, we can use the
more efficient bitmap ops instead of individual test/set bit ops.
