Michael Biebl dcce98a4bd Avoid strict DM interface version dependencies (#5519) ... Compiling against the dm-ioctl.h header as provided by the Linux kernel will embed the DM interface version number. Running an older kernel can result in an error like this on shutdown: Could not detach DM dm-11: ioctl mismatch, kernel(4.34.4), user(4.35.4) Work around this by shipping a local copy of dm-ioctl.h. We need at least the version from 3.13 for DM_DEFERRED_REMOVE [1], so bump the requirements in README accordingly.
