[GIT PULL] Folio fixes for 5.18

[Matthew Wilcox]

A mixture of odd changes that didn't quite make it into the original
pull and fixes for things that did.  Also the readpages changes had to
wait for the NFS tree to be pulled first.

The following changes since commit d888c83fcec75194a8a48ccd283953bdba7b2550:

  fs: fix fd table size alignment properly (2022-03-29 23:29:18 -0700)
