linux-next: manual merge of the folio tree with the ubifs-fixes tree

linux-next: manual merge of the folio tree with the ubifs-fixes tree

Hi all,

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

  fs/ubifs/file.c

between commit:

  3b67db8a6ca8 ("ubifs: Fix to add refcount once page is set private")

from the ubifs-fixes tree and commit:

  c337f2f4f746 ("ubifs: Convert from invalidatepage to invalidate_folio")

from the folio tree.

I fixed it up (I hope - 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.

This conflict is handled right.

This is now a conflict between the ubifs-fixes tree and Linus' tree.
