Bug Description
SRU Justification (Xenial):
Impact:
Due to kernel changes in 4.8, the version of flashcache in Xenial will not be able to do DKMS builds for hwe/hwe-edge kernels.
Fix:
Cherry-pick the compat-4.8 and init-bi-op-flags patches from the Zesty/17.04 version of the package.
Testcase:
- dkms build of flashcache module for 4.4 and 4.8 or 4.10
- quick functional test as described in bug #1714185

Module seems abandoned upstream[1] and the fixes to allow compilation which were made in Yakkety create no working module. Doing test setups "flashcache create -p back cdev1 <cache_dev> <backing_dev>" will create a /dev/mapper/cdev1 but trying to create an ext4 fs on it seems to write into the void. Nothing appears to be written.
Needs fixing before backporting.
