[GIT PULL 00/45] lightnvm updates for 4.20.

[Matias BjÃrling]

Hi Jens,

Please pick up the following patches for 4.20.

The changes include:

 - pblk trace support from Hans.
 - SPDX license header update from Javier.
 - Tons of refactoring patches from Javier, and me to cleanly abstract
   the 1.2 and 2.0 specs behind a common core interface.
 - Enable pblk to use a common interface to retrieve chunk metadata.
   From me.
 - Bug fixes from Hans, Javier, Jia-ju, Wei, Zhoujie, and me.

Thanks!,
Matias
