  ntfs3: add file I/O tracepoints (2026-10-28 08:09:20 +0100)

----------------------------------------------------------------
Changes for 7.4-rc1

The bulk of this cycle is hardening against corrupted or maliciously
crafted volumes. Most of these fixes come from fuzzing and KASAN
reports. The main areas are:

- $LogFile replay, where several unchecked on-disk sizes could make
  mount write past the MFT record buffer;
- MFT record and index parsing;
- extended attributes, where a bad $EA entry could leak up to 64K of
  kernel heap to userspace through getxattr().

Reading a damaged compressed file could also return uninitialized
page cache contents to userspace; that is fixed too.

A few fixes affect healthy volumes as well: a heap overflow in
fallocate(INSERT_RANGE) on small files, a use-after-free when a
WOF-compressed file is opened for writing during a concurrent read,
a lock-order deadlock in readdir, and stale disk data showing up in
newly allocated clusters of compressed files.

On the feature side there are new tracepoints covering mount, log
replay, lookup, directory index, allocation, iomap and file I/O.
There is also a new 'ugm' mount option (on by default): with ugm=0,
newly created files don't get the WSL uid/gid/mode extended
attributes, which Windows doesn't use.

The rest is smaller correctness fixes and cleanups.
