[PATCH] mpage_end_io_write() I/O error handling fix
When fsync() runs wait_on_page_writeback_range() it only inspects pages which are actually under I/O (PAGECACHE_TAG_WRITEBACK). If a page completed I/O prior to wait_on_page_writeback_range() looking at it, it is supposed to have recorded its I/O error state in the address_space. But mpage_mpage_end_io_write() forgot to set the address_space error flag in this case.
