+ * struct pstore_zone_info - pstore/zone back-end driver structure
+ *
+ * @owner: Module which is responsible for this back-end driver.
+ * @name: Name of the back-end driver.
+ * @total_size: The total size in bytes pstore/zone can use. It must be greater
+ * than 4096 and be multiple of 4096.
+ * @kmsg_size: The size of oops/panic zone. Zero means disabled, otherwise,
+ * it must be multiple of SECTOR_SIZE(512 Bytes).
+ * @max_reason: Maximum kmsg dump reason to store.
+ * @pmsg_size: The size of pmsg zone which is the same as @kmsg_size.
+ * @console_size:The size of console zone which is the same as @kmsg_size.
+ * @ftrace_size:The size of ftrace zone which is the same as @kmsg_size.
+ * @read: The general read operation. Both of the function parameters
+ * @size and @offset are relative value to storage.
+ * On success, the number of bytes should be returned, others
+ * mean error.
+ * @write: The same as @read, but the following error number:
+ * -EBUSY means try to write again later.
+ * -ENOMSG means to try next zone.
+ * @erase: The general erase operation for device with special removing
+ * job. Both of the function parameters @size and @offset are
+ * relative value to storage.
+ * Return 0 on success and others on failure.
+ * @panic_write:The write operation only used for panic case. It's optional
+ * if you do not care panic log. The parameters are relative
+ * value to storage.
+ * On success, the number of bytes should be returned, others
+ * excluding -ENOMSG mean error. -ENOMSG means to try next zone.
