The following fixes a rather embarassing bug in 2.6.16, and so should
go into 2.6.16.1, and 2.6.16-rc1.
Thanks,
NeilBrown
### Comments for Changeset
Both R1BIO_Barrier and R1BIO_Returned are 4 !!!!
This means that barrier requests don't get returned (i.e. b_endio
called) because it looks like they already have been.
