BugLink: http://bugs.launchpad.net/bugs/1713575

== SRU Justification ==
A regression in cxlflash driver was identified by IBM.  The regression was 
introduced by commit 565180723294 in v4.12-rc1.

The regression is fixed by mainline commit 
07a191f762a7b8d0db13c38036380927116e29bb.  This commit is in mailine
as of v4.14-rc1.  

The regression is that the ioctl DK_CAPI_VLUN_RESIZE can fail if the 
allocated vlun size is reduced from almost maximum capacity and then 
increased again.


== Fix ==
commit 07a191f762a7b8d0db13c38036380927116e29bb
