Subject[PATCH v3 4/4] Documentation: ABI: Fix documentation for mass_storage function
Date
Luns in mass storage function are identified using their id.
While creating lun's directory user cannot choose any arbitrary
name other than decimal value from 1 to FSG_MAX_LUNS.

Moreover, LUNs ids should be contiguous. This means that user
may remove only lun with max id and can create new lun
only if its id equals to max id + 1.
