I'm OK with this patch based on Madper's comment below. <snip> So i'd like to using fixed length. My dell xps has 128kb nvram space. and it at most store 126 pstore entries. So I think 1000 will be a safe value for count. For part, 100 should be okay. I don't think there will be a large kmsg and we must split it into more than 100 parts. <snip> > Does this need to be tagged for stable? > I think so.
