If we did not get a lease we can still return a single use cfid to the caller.
The cfid will not have has_lease set and will thus not be shared with any
other concurrent users and will be freed immediately when the caller
drops the handle.

This avoids extra roundtrips for servers that do not support directory leases
where they would first fail to get a cfid with a lease and then fallback
to try a normal SMB2_open()

Some servers may return that we got a lease in rsp->OplockLevel
but then in the lease context contradict this and say we got no lease
at all.  Thus we need to check the context if we have a lease.
Additionally, If we do not get a lease we need to make sure we close
the handle before we return an error to the caller.

The kernel is globally removing the ambiguous 0-length and 1-element
arrays in favor of flexible arrays, so that we can gain both compile-time
and run-time array bounds checking[1].

Replace the trailing 1-element array with a flexible array in the
following structures:

	struct cifs_spnego_msg
	struct cifs_quota_data
	struct get_dfs_referral_rsp
	struct file_alt_name_info
	NEGOTIATE_RSP
	SESSION_SETUP_ANDX

	FILE_DIRECTORY_INFO
	FILE_FULL_DIRECTORY_INFO
	SEARCH_ID_FULL_DIR_INFO
	FILE_BOTH_DIRECTORY_INFO

Replace the trailing 1-element array with a flexible array, but leave
the existing structure padding:

	FILE_ALL_INFO
	FILE_UNIX_INFO

Remove unused structures:

	struct gea
	struct gealist

Adjust all related size calculations to match the changes to sizeof().

The kernel is globally removing the ambiguous 0-length and 1-element
arrays in favor of flexible arrays, so that we can gain both compile-time
and run-time array bounds checking[1].

While struct fealist is defined as a "fake" flexible array (via a
1-element array), it is only used for examination of the first array
element. Walking the list is performed separately, so there is no reason
to treat the "list" member of struct fealist as anything other than a
single entry. Adjust the struct and code to match.

Additionally, struct fea uses the "name" member either as a dynamic
string, or is manually calculated from the start of the struct. Redefine
the member as a flexible array.

No machine code output differences are produced after these changes.

It seems that current windows servers and ksmbd would allow

And servers hopefully reject this in future.

  mm/filemap: fix page end in filemap_get_read_batch

Macro NILFS_SB2_OFFSET_BYTES, which computes the position of the second
superblock, underflows when the argument device size is less than 4096
bytes.  Therefore, when using this macro, it is necessary to check in
advance that the device size is not less than a lower limit, or at least
that underflow does not occur.

The current nilfs2 implementation lacks this check, causing out-of-bound
block access when mounting devices smaller than 4096 bytes:

 I/O error, dev loop0, sector 36028797018963960 op 0x0:(READ) flags 0x0
 phys_seg 1 prio class 2
 NILFS (loop0): unable to read secondary superblock (blocksize = 1024)

In addition, when trying to resize the filesystem to a size below 4096
bytes, this underflow occurs in nilfs_resize_fs(), passing a huge number
of segments to nilfs_sufile_resize(), corrupting parameters such as the
number of segments in superblocks.  This causes excessive loop iterations
in nilfs_sufile_resize() during a subsequent resize ioctl, causing
semaphore ns_segctor_sem to block for a long time and hang the writer

Users can specify the hugetlb page size in the mmap, shmget and
memfd_create system calls.  This is done by using 6 bits within the flags
argument to encode the base-2 logarithm of the desired page size.  The
routine hstate_sizelog() uses the log2 value to find the corresponding
hugetlb hstate structure.  Converting the log2 value (page_size_log) to
potential hugetlb page size is the simple statement:

	1UL << page_size_log

Because only 6 bits are used for page_size_log, the left shift can not be
greater than 63.  This is fine on 64 bit architectures where a long is 64
bits.  However, if a value greater than 31 is passed on a 32 bit
architecture (where long is 32 bits) the shift will result in undefined
behavior.  This was generally not an issue as the result of the undefined
shift had to exactly match hugetlb page size to proceed.

Recent improvements in runtime checking have resulted in this undefined
behavior throwing errors such as reported below.

Fix by comparing page_size_log to BITS_PER_LONG before doing shift.

Nick Bowler reported another sparc64 breakage after the young/dirty
persistent work for page migration (per "Link:" below).  That's after a
similar report [2].

It turns out page migration was overlooked, and it wasn't failing before
because page migration was not enabled in the initial report test
environment.

David proposed another way [2] to fix this from sparc64 side, but that
patch didn't land somehow.  Neither did I check whether there's any other
arch that has similar issues.

Let's fix it for now as simple as moving the write bit handling to be
after dirty, like what we did before.

Note: this is based on mm-unstable, because the breakage was since 6.1 and
we're at a very late stage of 6.2 (-rc8), so I assume for this specific
case we should target this at 6.3.

 "Three small fixes for 6.2 final:

   - Disable READ LOG DMA EXT for Samsung MZ7LH drives as these drives
     choke on that command, from Patrick.

   - Add Intel Tiger Lake UP{3,4} to the list of supported AHCI
     controllers (this is not technically a bug fix, but it is trivial
     enough that I add it here), from Simon.

     formatting was causing warnings from kernel-doc, from Randy"
