ext2: Fix ki_pos update for DIO buffered-io fallback case

commit 8abc712ea4867a81c860853048f24e511bbc20f2 upstream.

Commit "filemap: update ki_pos in generic_perform_write", made updating
of ki_pos

ext2: Fix ki_pos update for DIO buffered-io fallback case

commit 8abc712ea4867a81c860853048f24e511bbc20f2 upstream.

Commit "filemap: update ki_pos in generic_perform_write", made updating
of ki_pos into common code in generic_perform_write() function.
This also causes generic/091 to fail.
This happened due to an in-flight collision with:
fb5de4358e1a ("ext2: Move direct-io to use iomap"). I have chosen fixes tag
based on which commit got landed later to upstream kernel.

Fixes: 182c25e9c157 ("filemap: update ki_pos in generic_perform_write")

mm: remove enum page_entry_size

Remove the unnecessary encoding of page order into an enum and pass the
page order directly. That lets us get rid of pe_order().

The switch constructs have to be changed to if/else constructs to prevent
GCC from warning on builds with 3-level page tables where PMD_ORDER and
PUD_ORDER have the same value.

If you are looking at this commit because your driver stopped compiling,
look at the previous commit as well and audit your driver to be sure it
doesn't depend on mmap_lock being held in its ->huge_fault method.

Merge tag 'for-6.5/splice-2023-06-23' of git://git.kernel.dk/linux

Merge tag 'for-6.5/splice-2023-06-23' of git://git.kernel.dk/linux

Pull splice updates from Jens Axboe:
"This kills off ITER_PIPE to avoid a race between truncate,
iov_iter_revert() on the pipe and an as-yet incomplete DMA to a bio
with unpinned/unref'ed pages from an O_DIRECT splice read. This causes
memory corruption.

Instead, we either use (a) filemap_splice_read(), which invokes the
buffered file reading code and splices from the pagecache into the
pipe; (b) copy_splice_read(), which bulk-allocates a buffer, reads
into it and then pushes the filled pages into the pipe; or (c) handle
it in filesystem-specific code.

Summary:

- Rename direct_splice_read() to copy_splice_read()

- Simplify the calculations for the number of pages to be reclaimed
in copy_splice_read()

- Turn do_splice_to() into a helper, vfs_splice_read(), so that it
can be used by overlayfs and coda to perform the checks on the
lower fs

- Make vfs_splice_read() jump to copy_splice_read() to handle
direct-I/O and DAX

- Provide shmem with its own splice_read to handle non-existent pages
in the pagecache. We don't want a ->read_folio() as we don't want
to populate holes, but filemap_get_pages() requires it

- Provide overlayfs with its own splice_read to call down to a lower
layer as overlayfs doesn't provide ->read_folio()

- Provide coda with its own splice_read to call down to a lower layer
as coda doesn't provide ->read_folio()

- Direct ->splice_read to copy_splice_read() in tty, procfs, kernfs
and random files as they just copy to the output buffer and don't
splice pages

- Provide wrappers for afs, ceph, ecryptfs, ext4, f2fs, nfs, ntfs3,
ocfs2, orangefs, xfs and zonefs to do locking and/or revalidation

- Make cifs use filemap_splice_read()

- Replace pointers to generic_file_splice_read() with pointers to
filemap_splice_read() as DIO and DAX are handled in the caller;
filesystems can still provide their own alternate ->splice_read()
op

- Remove generic_file_splice_read()

- Remove ITER_PIPE and its paraphernalia as generic_file_splice_read
was the only user"

ext2: Move direct-io to use iomap

This patch converts ext2 direct-io path to iomap interface.
- This also takes care of DIO_SKIP_HOLES part in which we return -ENOTBLK
from ext2_iomap_begin(), in case if the write is done on a hole.
- This fallbacks to buffered-io in case of DIO_SKIP_HOLES or in case of
a partial write or if any error is detected in ext2_iomap_end().
We try to return -ENOTBLK in such cases.
- For any unaligned or extending DIO writes, we pass
IOMAP_DIO_FORCE_WAIT flag to ensure synchronous writes.
- For extending writes we set IOMAP_F_DIRTY in ext2_iomap_begin because
otherwise with dsync writes on devices that support FUA, generic_write_sync
won't be called and we might miss inode metadata updates.
- Since ext2 already now uses _nolock vartiant of sync write. Hence
there is no inode lock problem with iomap in this patch.
- ext2_iomap_ops are now being shared by DIO, DAX & fiemap path

ext2: Use generic_buffers_fsync() implementation

Next patch converts ext2 to use iomap interface for DIO.
iomap layer can call generic_write_sync() -> ext2_fsync() from
iomap_dio_complete while still holding the inode_lock().

Now writeback from other paths doesn't need inode_lock().
It seems there is also no need of an inode_lock() for
sync_mapping_buffers(). It uses it's own mapping->private_lock
for it's buffer list handling.
Hence this patch is in preparation to move ext2 to iomap.
This uses generic_buffers_fsync() which does not take any inode_lock()
in ext2_fsync().
