[PATCH 06/13] lightnvm: pblk: Ensure that erase is chunk aligned

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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