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.

move_extent_per_page() currently assumes that each folio is the size of
PAGE_SIZE and only copies data for one page. ext4_move_extents() should
call move_extent_per_page() for each page. To support larger folios,
simply modify the calculations for the block start and end offsets
within the folio based on the provided range of 'data_offset_in_page'
and 'block_len_in_page'. This function will continue to handle PAGE_SIZE
of data at a time and will not convert this function to manage an entire
folio. Additionally, we use the source folio to copy data, so it doesn't
matter if the source and dest folios are different in size.

The journal credits calculation in ext4_ext_index_trans_blocks() is
currently inadequate. It only multiplies the depth of the extents tree
and doesn't account for the blocks that may be required for adding the
leaf extents themselves.
After enabling large folios, we can easily run out of handle credits,
triggering a warning in jbd2_journal_dirty_metadata() on filesystems
with a 1KB block size. This occurs because we may need more extents when
iterating through each large folio in
ext4_do_writepages()->mpage_map_and_submit_extent(). Therefore, we
should modify ext4_ext_index_trans_blocks() to include a count of the
leaf extents in the worst case as well.

Luis and David are reporting that after running generic/750 test for 90+
hours on 2k ext4 filesystem, they are able to trigger a warning in
jbd2_journal_dirty_metadata() complaining that there are not enough
credits in the running transaction started in ext4_do_writepages().
Indeed the code in ext4_do_writepages() is racy and the extent tree can
change between the time we compute credits necessary for extent tree
computation and the time we actually modify the extent tree. Thus it may
happen that the number of credits actually needed is higher. Modify
ext4_ext_index_trans_blocks() to count with the worst case of maximum
tree depth. This can reduce the possible number of writers that can
operate in the system in parallel (because the credit estimates now won't
fit in one transaction) but for reasonably sized journals this shouldn't
really be an issue. So just go with a safe and simple fix.

To add a generic support for future SoCs where one or more video pipelines
can get truncated from the parent register space, move the video plane
related information to vid_info struct which will also have a field to

doing the same on MT8390 to lessen eventual ABI breakages that may
