[ndctl,v5,1/5] ndctl: Introduce libndctl-nfit.h

Commit Message

Gotou, Yasunori/五島 康文 Sept. 7, 2017, 5:02 a.m. UTC

This patch introduces libndctl-nfit.h.

Since these command can be executed via ND_CMD_CALL,
libndctl.h which is shared between ndctl command and kernel does not
have to include these defintions.

So, libndctl-nfit.h, which is defined for only ndctl, is created instead.
