Hi Jes, Coly Following patchset modifies some parts of IMSM creation to ensure that member's order is always same. It is ISM metadata requirement. Additionally, as discussed with Jes I've started to implement more modern error handling, by adding special enum for IMSM. Will be great to hear any comments and opinion. I've tested it with our internal test scope, no regression observed.
