pstore/ram: verify ramoops header before saving record 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. Signed-off-by: Ben Zhang <benzh@chromium.org> Signed-off-by: Tony Luck <tony.luck@intel.com>
