ocfs2: fix pagecache truncation prior to reflink Prior to remapping blocks, it is necessary to remove pages from the destination file's page cache. Unfortunately, the truncation is not aggressive enough -- if page size > block size, we'll end up zeroing subpage blocks instead of removing them. So, round the start offset down and the end offset up to page boundaries. We already wrote all the dirty data so the larger range should be fine. Signed-off-by: Darrick J.
