Description

I would like to submit some patches related to sgpdd survey.

The main one is to enhance sgpdd-survey to support multiple servers sharing a single storage array.

Also some ideas, I would like to discuss with other users concerned:

• replace the use of raw device (which is deprecated) by the use of O_DIRECT option
• allow optional placement of sgp_dd commands according to accessed device's NUMA node
