Based on kerneloops data, this bug seems to have been fixed in 2.6.27:
http://www.kerneloops.org/search.php?search=clone_endio&btnG=Function+Search

Unfortunately I cannot find a specific fix.  The changes made to
dm-multipath between 2.6.26 and 2.6.27 are extensive and dependent on
SCSI layer changes.
