Please write a proper commit message. For now I am looking for input from linux community regarding approach used in my solution. I will convert RFC to PATCH and most suitable header I will attach with each patch. Hope it is OK. Current RFC has changes included for mpt3sas. Same logic will be followed for megaraid_sas as well. Just for reference I have posted changes of mpt3sas and not included megaraid_sas. > > Thanks, > Johannes > > -- > Johannes Thumshirn Storage > jthumshirn@suse.de +49 911 74053 689 > SUSE LINUX GmbH, Maxfeldstr. 5, 90409 N=C3=BCrnberg > GF: Felix Imend=C3=B6rffer, Jane Smithard, Graham Norton HRB 21284 (AG > N=C3=BCrnberg) Key fingerprint =3D EC38 9CAB C2C4 F25D 8600 D0D0 0393 969= D 2D76 > 0850
