Ritesh Harjani (IBM) 3a16dc3ea8 iomap: Fix iomap_adjust_read_range for plen calculation ... [ Upstream commit f5ceb1bbc9 ] If the extent spans the block that contains i_size, we need to handle both halves separately so that we properly zero data in the page cache for blocks that are entirely outside of i_size. But this is needed only when i_size is within the current folio under processing. "orig_pos + length > isize" can be true for all folios if the mapped extent length is greater than the folio size. That is making plen to break for every folio instead of only the last folio. So use orig_plen for checking if "orig_pos + orig_plen > isize".
