staging: pi433: goto abort when setting failed in tx_thread

tx_thread in pi433 works for transmitting. it reads tx_cfg and data
stored in kfifo put in pi433_write() and transmits. If it exits,
pi433_write() just store its data and no one transmits data. So,
tx_thread should not exit even when it failed for setting registers.
It seems that it's okay to go to abort and continue to loop and wait for
writing.

Pull io_uring fixes from Jens Axboe:
 "This one looks a bit bigger than it is, but that's mainly because 2/3

  We've had a few folks using them and finding it confusing that the way
  to close them is through using -1 for file update, this just brings
  API symmetry for direct descriptors. Hence I think we should just do
  this now and have a better API for 5.15 release. There's some room for

mm: fix uninitialized use in overcommit_policy_handler

We get an unexpected value of /proc/sys/vm/overcommit_memory after
running the following program:

  int main()
  {
      int fd = open("/proc/sys/vm/overcommit_memory", O_RDWR);
      write(fd, "1", 1);
      write(fd, "2", 1);
      close(fd);
  }

write(fd, "2", 1) will pass *ppos = 1 to proc_dointvec_minmax.
proc_dointvec_minmax will return 0 without setting new_policy.

  t.data = &new_policy;
  ret = proc_dointvec_minmax(&t, write, buffer, lenp, ppos)
      -->do_proc_dointvec
         -->__do_proc_dointvec
              if (write) {
                if (proc_first_pos_non_zero_ignore(ppos, table))
                  goto out;

  sysctl_overcommit_memory = new_policy;

so sysctl_overcommit_memory will be set to an uninitialized value.

Check whether new_policy has been changed by proc_dointvec_minmax.

kasan: always respect CONFIG_KASAN_STACK

Currently, the asan-stack parameter is only passed along if
CFLAGS_KASAN_SHADOW is not empty, which requires KASAN_SHADOW_OFFSET to
be defined in Kconfig so that the value can be checked.  In RISC-V's
case, KASAN_SHADOW_OFFSET is not defined in Kconfig, which means that
asan-stack does not get disabled with clang even when CONFIG_KASAN_STACK
is disabled, resulting in large stack warnings with allmodconfig:

Ensure that the value of CONFIG_KASAN_STACK is always passed along to

CONFIG_KASAN_STACK is disabled.

mm: fs: invalidate bh_lrus for only cold path

The kernel test robot reported the regression of fio.write_iops[1] with
commit 8cc621d2f45d ("mm: fs: invalidate BH LRU during page migration").

Since lru_add_drain is called frequently, invalidate bh_lrus there could
increase bh_lrus cache miss ratio, which needs more IO in the end.

This patch moves the bh_lrus invalidation from the hot path( e.g.,
zap_page_range, pagevec_release) to cold path(i.e., lru_add_drain_all,
lru_cache_disable).

Zhengjun Xing confirmed
 "I test the patch, the regression reduced to -2.9%"

mm/shmem.c: fix judgment error in shmem_is_huge()

In the case of SHMEM_HUGE_WITHIN_SIZE, the page index is not rounded up
correctly.  When the page index points to the first page in a huge page,
round_up() cannot bring it to the end of the huge page, but to the end
of the previous one.

An example:

HPAGE_PMD_NR on my machine is 512(2 MB huge page size).  After
allcoating a 3000 KB buffer, I access it at location 2050 KB.  In
shmem_is_huge(), the corresponding index happens to be 512.  After
rounded up by HPAGE_PMD_NR, it will still be 512 which is smaller than
i_size, and shmem_is_huge() will return true.  As a result, my buffer
takes an additional huge page, and that shouldn't happen when
shmem_enabled is set to within_size.

mm, hwpoison: add is_free_buddy_page() in HWPoisonHandlable()

Commit fcc00621d88b ("mm/hwpoison: retry with shake_page() for
unhandlable pages") changed the return value of __get_hwpoison_page() to
retry for transiently unhandlable cases.  However, __get_hwpoison_page()
currently fails to properly judge buddy pages as handlable, so hard/soft
offline for buddy pages always fail as "unhandlable page".  This is
totally regrettable.

So let's add is_free_buddy_page() in HWPoisonHandlable(), so that
__get_hwpoison_page() returns different return values between buddy
pages and unhandlable pages as intended.

io_uring: make OP_CLOSE consistent with direct open

From recently open/accept are now able to manipulate fixed file table,
but it's inconsistent that close can't. Close the gap, keep API same as
with open/accept, i.e. via sqe->file_slot.
