Merge tag 'vfs-6.13.usercopy' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull copy_struct_to_user helper from Christian Brauner:
 "This adds a copy_struct_to_user() helper which is a companion helper
  to the already widely used copy_struct_from_user().

  It copies a struct from kernel space to userspace, in a way that
  guarantees backwards-compatibility for struct syscall arguments as
  long as future struct extensions are made such that all new fields are
  appended to the old struct, and zeroed-out new fields have the same
  meaning as the old struct.

  The first user is sched_getattr() system call but the new extensible
  pidfs ioctl will be ported to it as well"

* tag 'vfs-6.13.usercopy' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  sched_getattr: port to copy_struct_to_user
  uaccess: add copy_struct_to_user helper

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
