I've updated John's RFC crash patch to match 5.10-rc4
kernel.
Changes from the RFC patch:
- followed the following kernel commits
cfe2790b163a ("printk: move printk_info into separate array")
74caba7f2a06 ("printk: move dictionary keys to dev_printk_info")
f35efc78add6 ("printk: remove dict ring")
- moved the added members in offset_table and size_table to the end
of them
- print offsets and sizes with "help -o" option
- support "log -T" option
Thank you for this work. I've attached a followup "crash" patch to
correctly interpret the state value. With this followup patch applied,
this passes all my tests.
Note that support for "./crash --log ./vmcore" is still not
implemented. That can be done in a separate patch.
