ext4: enable large folio for regular file

Browse source

Besides fsverity, fscrypt, and the data=journal mode, ext4 now supports
large folios for regular files. Enable this feature by default. However,
since we cannot change the folio order limitation of mappings on active
inodes, setting the journal=data mode via ioctl on an active inode will
not take immediate effect in non-delalloc mode.
