Merge tag 'vfs-6.7.xattr' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Pull vfs xattr updates from Christian Brauner:
 "The 's_xattr' field of 'struct super_block' currently requires a
  mutable table of 'struct xattr_handler' entries (although each handler
  itself is const). However, no code in vfs actually modifies the
  tables.

  This changes the type of 's_xattr' to allow const tables, and modifies
  existing file systems to move their tables to .rodata. This is
  desirable because these tables contain entries with function pointers
  in them; moving them to .rodata makes it considerably less likely to
  be modified accidentally or maliciously at runtime"
