| Subject | [PATCH] lightnvm: Add error code for bad write pointer |
| Message-ID | <umFKO-lj-19@gated-at.bofh.it> |
Add new error code introduced on the OCSSD spec 2.0 for write pointer
mismatch on the device side. This indicates to the host that a write on
a block (chunk) is not respecting the required sequentiality.

I'll wait to re-post until we have the spec out. Javier
