Merge tag 'affs-for-6.6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull affs updates from David Sterba: "Two minor updates for AFFS: - reimplement writepage() address space callback on top of migrate_folio() - fix a build warning, local parameters 'toupper' collide with the standard ctype.h name" * tag 'affs-for-6.6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: affs: rename local toupper() to fn() to avoid confusion affs: remove writepage implementation
