using the kmsg_dumper.

Hi, I want to store the kernel logs just before somebody calls the machine reset. I was exploring several ways to implement it. When i am going through the code in printk.c i saw a function kmsg_dump(), which says it will dump the kmsg buffer to all dump devices attached to it. What is a dump device? can we write them to our flash. I also saw in panic() implementation they are using this. TO which dump device those messages will be stored. -- With regards, Sandeep Kumar Anantapalli,
