[PATCH v2 4/8] lightnvm: pblk: Ensure that erase is chunk aligned

[Igor Konopko]

In current pblk implementation of erase command there is a chance
that the sector bits are set to some random values for erase PPA.
This is unexpected situation, since erase shall be always chunk
aligned based on OCSSD 2.0 specification. This patch fixes that issue.
