Such a change would would indeed break XFS, in exactly the way you
suggest Jan - the realtime subvolume does typically use a different
blocksize from the data subvolume (the realtime extent size is used,
and this can be set per-inode too), and there would now be no way to
distinguish this preferred IO size difference.
It can be made into an inode operation:
if (inode->i_ops->getblksize)
return inode->i_ops->getblksize(inode);
else
return inode->i_sb->s_blksize;
Trading some efficiency for space.
