ceph_writepages_start() reads inode->i_size in two places. It can get different values between successive read, because truncate can change inode->i_size at any time. The race can lead to mismatch between data length of osd request and pages marked as writeback. When osd request finishes, it clear writeback page according to its data length. So some pages can be left in writeback state forever. The fix is only read inode->i_size once, save its value to a local variable and use the local variable when i_size is needed.
