fs/ntfs3: Add functions to modify LE bitmaps
__bitmap_set/__bitmap_clear only works with bitmaps in CPU order.
Define a variant of these functions in ntfs3 to handle modifying bitmaps
read from the filesystem.

fs/ntfs3: Add windows_names mount option

0a4ee51818 mm: remove cleancache
Patch series "remove Xen tmem leftovers".

Since the removal of the Xen tmem driver in 2019, the cleancache hooks
are entirely unused, as are large parts of frontswap.  This series
against linux-next (with the folio changes included) removes
cleancaches, and cuts down frontswap to the bits actually used by zswap.

This patch (of 13):

The cleancache subsystem is unused since the removal of Xen tmem driver
in commit 814bbf49dc ("xen: remove tmem driver").

fs/ntfs3: Add missing headers and forward declarations to ntfs_fs.h
We do not have headers at all in this file. We should have them so that
not every .c file needs to include all of the stuff which this file need
for building. This way we can remove some headers from other files and
get better picture what is needed. This can save some compilation time.
And this can help if we sometimes want to separate this one big header.

Also use forward declarations for structs and enums when it not included
straight with include and it is used in function declarations input.
This will prevent possible compiler warning:
  xxx declared inside parameter list will not be visible
  outside of this definition or declaration

Here is list which I made when parsing this. There is not necessarily
all example from this header file, but this just proofs we need it.

<linux/blkdev.h> SECTOR_SHIFT

fs/ntfs3: Show uid/gid always in show_options()
Show options should show option according documentation when some value
is not default or when ever coder wants. Uid/gid are problematic because
it is hard to know which are defaults. In file system there is many
different implementation for this problem.

Some file systems show uid/gid when they are different than root, some
when user has set them and some show them always. There is also problem
that what if root uid/gid change. This code just choose to show them
always. This way we do not need to think this any more.

Use pointer to mount options. We want to do this because we will use new

spi it is enough that we will allocate just mount options.

Please note that we can do example remount lot cleaner but things will
change in next patch so this should be just functional.

Merge NTFSv3 filesystem from Konstantin Komarov:
 "This patch adds NTFS Read-Write driver to fs/ntfs3.

  Having decades of expertise in commercial file systems development and
  huge test coverage, we at Paragon Software GmbH want to make our
  contribution to the Open Source Community by providing implementation
  of NTFS Read-Write driver for the Linux Kernel.

  This is fully functional NTFS Read-Write driver. Current version works
  with NTFS (including v3.1) and normal/compressed/sparse files and
  supports journal replaying.

  We plan to support this version after the codebase once merged, and
  add new features and fix bugs. For example, full journaling support
  over JBD will be added in later updates"

Rename now works "Add new name and remove old name".
"Remove old name and add new name" may result in bad inode
if we can't add new name and then can't restore (add) old name.

fs/ntfs3: Restyle comments to better align with kernel-doc
Capitalize comments and end with period for better reading.

Also function comments are now little more kernel-doc style. This way we
can easily convert them to kernel-doc style if we want. Note that these
are not yet complete with this style. Example function comments start
with /* and in kernel-doc style they start /**.

Use imperative mood in function descriptions.

Change words like ntfs -> NTFS, linux -> Linux.

Use "we" not "I" when commenting code.

fs/ntfs3: Do not use driver own alloc wrappers
Problem with these wrapper is that we cannot take off example GFP_NOFS
flag. It is not recomended use those in all places. Also if we change
one driver specific wrapper to kernel wrapper then it would look really
weird. People should be most familiar with kernel wrappers so let's just
use those ones.

Driver specific alloc wrapper also confuse some static analyzing tools,
good example is example kernels checkpatch tool. After we converter
these to kernel specific then warnings is showed.

Following Coccinelle script was used to automate changing.

fs/ntfs3: Use kernel ALIGN macros over driver specific
The static checkers (Smatch) were complaining because QuadAlign() was
buggy.  If you try to align something higher than UINT_MAX it got
truncated to a u32.

Smatch warning was:
	fs/ntfs3/attrib.c:383 attr_set_size_res()
	warn: was expecting a 64 bit value instead of '~7'

So that this will not happen again we will change all these macros to
kernel made ones. This can also help some other static analyzing tools
to give us better warnings.

Patch was generated with Coccinelle script and after that some style
issue was hand fixed.

Coccinelle script:
