From 23c85094fe1895caefdd19ef624ee687ec5f4507 Mon Sep 17 00:00:00 2001 From: Omar Sandoval Date: Tue, 21 Aug 2018 21:55:20 -0700 Subject: proc/kcore: add vmcoreinfo note to /proc/kcore The vmcoreinfo information is useful for runtime debugging tools, not just for crash dumps. A lot of this information can be determined by other means, but this is much more convenient, and it only adds a page at most to the file.
