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
