Merge tag 'vfs-7.0-rc1.leases' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs lease updates from Christian Brauner:
 "This contains updates for lease support to require filesystems to
  explicitly opt-in to lease support

  Currently kernel_setlease() falls through to generic_setlease() when a
  a filesystem does not define ->setlease(), silently granting lease
  support to every filesystem regardless of whether it is prepared for
  it.

  This is a poor default: most filesystems never intended to support
  leases, and the silent fallthrough makes it impossible to distinguish
  "supports leases" from "never thought about it".

  This inverts the default. It adds explicit

	.setlease = generic_setlease;

  assignments to every in-tree filesystem that should retain lease
  support, then changes kernel_setlease() to return -EINVAL when
  ->setlease is NULL.

  With the new default in place, simple_nosetlease() is redundant and
  is removed along with all references to it"
