Hi,
This series makes a few improvements to /proc/kcore. Patches 1 and 2 are prep patches. Patch 3 is a fix/cleanup. Patch 4 is another prep patch. Patches 5 and 6 are optimizations to ->read(). Patch 7 adds vmcoreinfo to /proc/kcore. This series is based on v4.18-rc3. Please consider it for v4.19.
Thanks!
