Subject: xfs: disable large folio support in xfile_create
Date: Wed, 10 Jan 2024 10:21:09 +0100

The xfarray code will crash if large folios are force enabled using:

   echo force > /sys/kernel/mm/transparent_hugepage/shmem_enabled

Fixing this will require a bit of an API change, and prefeably sorting out
the hwpoison story for pages vs folio and where it is placed in the shmem
API.  For now use this one liner to disable large folios.
