This means that there is no need to include your zram patchset to
the upcoming release of crash?  We can wait for it during this week..

Yes, I will do.

Bhupesh and Lianbo,

My understanding is that we cannot remove (replace) the old version of gcore
(crash-gcore-command-1.5.1.tar.gz) on https://github.com/crash-utility/crash-extensions
because distributors might download it directly.  so I will

- only add crash-gcore-command-1.6.0.tar.gz to the crash-extensions repo
  (do not remove crash-gcore-command-1.5.1.tar.gz)
- update https://crash-utility.github.io/extensions.html to link to 1.6.0,
  and etc.

If you have any problems, please let me know.

Thanks,
Kazu
