Sorry, I'm based on the latest branch of the erofs repository.
https://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs.git/log/?h=dev-test
I think I can resend based on mainline.

So it seems better to change to DIV_ROUND_UP(i_size_read_inode(), i_blocksize(inode))?

How about the following msg?
Use i_blockmask() to simplify code. BTW convert ocfs2_is_io_unaligned
to return bool type and the fact that the value will be the same
(i.e. that ->i_blkbits is never changed by ocfs2).
A small question, whether this series of changes will be merged
into each fs branch or all merged into vfs?
Thx,
