Subject: linux-next: manual merge of the vfs tree with the vfs-brauner tree

Hi all,

Today's linux-next merge of the vfs tree got a conflict in:

  Documentation/filesystems/porting.rst

between commit:

  2b10994be716b ("filelock: default to returning -EINVAL when ->setlease operation is NULL")

from the vfs-brauner tree and commit:

  e6d50234ccb9f ("non-consuming variant of do_renameat2()")

from the vfs tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

 +The ->setlease() file_operation must now be explicitly set in order to provide
 +support for leases. When set to NULL, the kernel will now return -EINVAL to
 +attempts to set a lease. Filesystems that wish to use the kernel-internal lease
 +implementation should set it to generic_setlease().

+ fs/namei.c primitives that consume filesystem references (do_renameat2(),
+ do_linkat(), do_symlinkat(), do_mkdirat(), do_mknodat(), do_unlinkat()
+ and do_rmdir()) are gone; they are replaced with non-consuming analogues
+ (filename_renameat2(), etc.)
+ Callers are adjusted - responsibility for dropping the filenames belongs
+ to them now.
