Subject: [PATCH 2/2] null_blk: Update ida_simple_get()/ida_simple_remove() to the newer ida API

ida_simple_get() and ida_simple_remove() are deprecated. Use ida_alloc()
and ida_free() instead. It is less verbose.

Hi,

I was not aware of it...

Do you plan to send patches for all ida_xxx() changes that are needed
all over the kernel or is it only limited to
'drivers/block/null_blk/main.c'?

(read: should I spend time on it, or is the phasing out of this
deprecated API is already on the todo list of someone)
