./include/linux/greybus/.__afs3C95: File removed before we read it
The find warning doesn't seem to cause a problem.
Fix this by telling tar when called from in gen_kheaders.sh to exclude such
files. This only affects afs and nfs; cifs uses the Windows Hidden
attribute to prevent the file from
eturn.
Note that this does not try to fix the problem.

the decryption can happen in parallel).
There is a disadvantage in that we're losing the ability to decrypt and
unlock things on an as-things-arrive basis which may affect some
applications.

(10) Enable caching on directories.
(11) Only set the upload key for writeback for regular files.
Notes:
(*) We keep the ->release_folio(), ->invalidate_folio() and
->migrate_folio() ops as we set the mapping pointer on the folio.
Add support for caching the content of a file that contains a single
monolithic object that must be read/written with a single I/O operation,
such as an AFS directory.
