The quilt patch titled Subject: xfs: disable large folio support in xfile_create has been removed from the -mm tree. Its filename was xfs-disable-large-folio-support-in-xfile_create.patch
This patch was dropped because it is obsolete
------------------------------------------------------ From: Christoph Hellwig hch@lst.de 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.
