[patch 0/2] dm-delay flush patches

[Mikulas Patocka <mpatocka@redhat.com>]

Hi

These patches extend dm-delay, so that the user can select separate delay
for flush requests.

Zdenek needs to create a device with one slow sector for the purpose of
testing, so he creates a device that has three targets:
linear,delay,linear

The problem with this setup is that flushes are forwarded to all three
devices and it skews test results. So I created this patchset that allows
to set zero delay for flushes.
