Re: [PATCH] block: remove non-existent partition dev_t return from blk_lookup_devt

NAK.

Don't do this.  Md at least has a reason for doing this silly things
as in the code as written in the 1990s where people did not know better.

The dm-initwait code has no such excuse as it was written recently and
explicitly ignored the rules to not use this early dev_t lookup code that
is known to be broken.  You now have to live with the fallout because you
decided to you this broken code.  Stop using it if you care.

If there's one thing we need to do is to warn everyone in the Kconfig
and boot time dmesg that dm-initwait is broken.
