The generic manager should be called the general media manager, and instead of using the rather long name of "gennvm" in front of each data structures, use "gen" instead to shorten it. Update the description of the media manager as well to make the media manager purpose clearer. Signed-off-by: Matias Bjørling <m@bjorling.me> Signed-off-by: Jens Axboe <axboe@fb.com>

Open-Channel SSDs implement a set of extension to SSDs, that

exposes direct access to the underlying non-volatile memory.

If you say N, all options in this submenu will be skipped and disabled

|
|
Non-volatile memory media manager for Open-Channel SSDs that implements
|
|
physical media metadata management and block provisioning API.
|
|
|
|
This is the standard media manager for using Open-Channel SSDs, and
|
|
required for targets to be instantiated.

tristate "Round-robin Hybrid Open-Channel SSD target"

---help---
|
|
Allows an open-channel SSD to be exposed as a block device to the
|
|
host. The target is implemented using a linear mapping table and
|
|
cost-based garbage collection. It is optimized for 4K IO sizes.
