Aleksandr Yashkin 45b0a5affc pstore/ram: Write new dumps to start of recycled zones ... commit 9e5f1c19800b808a37fb9815a26d382132c26c3d upstream. The ram_core.c routines treat przs as circular buffers. When writing a new crash dump, the old buffer needs to be cleared so that the new dump doesn't end up in the wrong place (i.e. at the end). The solution to this problem is to reset the circular buffer state before writing a new Oops dump.
