This series fixes pfn_valid() for ZONE_DEVICE based memory and also improves
its performance for normal hotplug memory. While here, it also reorganizes
pfn_valid() on CONFIG_SPARSEMEM. This series is based on v5.12-rc1.

A struct folio refers to an entire (possibly compound) page. A function
which takes a struct folio argument declares that it will operate on the
entire compound page, not just PAGE_SIZE bytes. In return, the caller
guarantees that the pointer it is passing does not point to a tail page.

Hi xiaoming,
the path can only fix the endless loop problem. it can't fix the meaningless

if we set llcp_sock->service_name to meaningless string, the connect will be failed. and

Sorry about that, I must have figured that out myself.

Hi Linus,
More may show up but this is what I have at this staged. These are
based on the commit in your tree where the swapfile issue is fixed,
and neither of the merged trees are in the bad area.
Otherwise just a single nouveau regression fix, and a bunch of amdgpu fixes.
Dave.

Actually Linux kernel already provide function "kernel_read_file_id_str()"
for secure access in "kernel_read_file.h".
And, in "parse_exclude()" function, it's better to use
BUILD_BUG_ON(ARRAY_SIZE(kernel_read_file_str) - 1 ==
ARRAY_SIZE(ignore_read_file_id));
to make sure

When bch_bio_alloc_pages() fails, no error return code of
cached_dev_cache_miss() is assigned.
To fix this bug, ret is assigned with -ENOMEN as error return code.

My static analysis tool reports that no error return code is assigned in
error handling code of msb_resume().
However, many other drivers assign error return code in xxx_resume(),
such as sky2_resume() and e1000_resume().
I wonder whether this is intentional?
Best wishes,
