NeilBrown 039b7225e6 md: allow creation of mdNNN arrays via md_mod/parameters/new_array ... The intention when creating the "new_array" parameter and the possibility of having array names line "md_HOME" was to transition away from the old way of creating arrays and to eventually only use this new way. The "old" way of creating array is to create a device node in /dev and then open it. The act of opening creates the array. This is problematic because sometimes the device node can be opened when we don't want to create an array. This can easily happen when some rule triggered by udev looks at a device as it is being destroyed. The node in /dev continues to exist for a short period after an array is stopped, and opening it during this time recreates the array (as an inactive array). Unfortunately no clear plan for the transition was created. It is now time to fix that. This patch allows devices with numeric names, like "md999" to be created by writing to "new_array". This will only work if the minor number given is not already in use. This will allow mdadm to support the creation of arrays with numbers > 511 (currently not possible) by writing to new_array. mdadm can, at some point, use this approach to create *all* arrays, which will allow the transition to only using the new-way.
