    pstore/ram: verify ramoops header before saving record · e036bd33
    Ben Zhang authored May 21, 2015
    
    
    On some devices the persistent memory contains junk after a cold boot,
    and /dev/pstore/dmesg-ramoops-* are created with random data which is
    not the result of a kernel crash.
    
    This patch adds a ramoops header check and skips any
    persistent_ram_zone that does not have a valid header.
