[2.6-BK-URL] NTFS: 2.1.19 sparse annotation, cleanups and a bugfix

[Anton Altaparmakov <aia21@cam.ac.uk>]

Hi Linus, please do a

	bk pull bk://linux-ntfs.bkbits.net/ntfs-2.6

This includes the (off-list) discussed NTFS sparse annotations, some other
cleanups and a fix for a bug found by the bitwise sparse annotations.  (-:

Please apply.  Thanks!

For the benefit of non-BK users and to make code review easier, I am
sending each ChangeSet in a separate email as a diff -u style patch.

Best regards,

	Anton

   NTFS: - Remove BKL use from ntfs_setattr() syncing up with the rest of the
           kernel.
         - Update ->setattr (fs/ntfs/inode.c::ntfs_setattr()) to refuse to
           change the uid, gid, and mode of an inode as we do not support NTFS
           ACLs yet.

   NTFS: Get rid of the ugly transparent union in fs/ntfs/dir.c::ntfs_readdir()
         and ntfs_filldir() as per suggestion from Al Viro.

<aia21@cantab.net> (04/09/23 1.1952)
   NTFS: - Update ->truncate (fs/ntfs/inode.c::ntfs_truncate()) to check if the
           inode size has changed and to only output an error if so.
         - Rename fs/ntfs/attrib.h::attribute_value_length() to ntfs_attr_size().

<aia21@cantab.net> (04/09/24 1.1952.1.1)
   NTFS: Begin of sparse annotations: new data types and endianness conversion.
   
   - Add le{16,32,64} as well as sle{16,32,64} data types to fs/ntfs/types.h.
   - Change ntfschar to be le16 instead of u16 in fs/ntfs/types.h.
   - Add le versions of VCN, LCN, and LSN called leVCN, leLCN, and leLSN,
     respectively, to fs/ntfs/types.h.
   - Update endianness conversion macros in fs/ntfs/endian.h to use the
     new types as appropriate.
   - Do proper type casting when using sle64_to_cpup() in fs/ntfs/dir.c
     and index.c.

<aia21@cantab.net> (04/09/24 1.1952.1.2)
   NTFS: Continuing sparse annotations: finish data types and header files.
   
   - Add leMFT_REF data type to fs/ntfs/layout.h.
   - Update all NTFS header files with the new little endian data types.
     Affected files are fs/ntfs/layout.h, logfile.h, and time.h.
   - Do proper type casting when using ntfs_is_*_recordp() in
     fs/ntfs/logfile.c, mft.c, and super.c.

<aia21@cantab.net> (04/09/24 1.1952.1.3)
   NTFS: Finish off sparse annotation.
   
   - Fix all the sparse bitwise warnings.  Had to change all the enums
     storing little endian values to #defines because we cannot set enums
     to be little endian so we had lots of bitwise warnings from sparse.

<aia21@cantab.net> (04/09/24 1.1952.1.4)
   NTFS: 2.1.19 - Many cleanups, improvements, and a minor bug fix.
   
   - Fix bug found by the new sparse bitwise warnings where the default
     upcase table was defined as a pointer to wchar_t rather than ntfschar
     in fs/ntfs/ntfs.h and super.c.

   NTFS: Fix a stupid bug where I forgot to actually do the attribute lookup
         and then went and used the looked up attribute...  Ooops.
