Hi all,
I've created some GDB commands I think useful when I debug
some memory issues and kernel module issue.
For memory issue, we would like to get slabinfo, slabtrace,
page_owner and vmallocinfo to debug the memory issues.
For module issue, we would like to query kernel module name
when we get a module text address and load module
symbol by specific path.
This patchset is based on v6.5-rc3.
Patch 1-2:
- Add kernel module releated command.
Patch 3-5:
- Prepares for the memory-releated command.
Patch 6-8:
- Add memory-related commands.
