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.
Patch 1-2:
- Add kernel module related command.
Patch 3-5:
- Prepares for the memory-related command.
Patch 6-8:
- Add memory-related commands.
V1->V2:
- Fix s390 build error with defconfig (Stephen)
- Use freeptr_t structure for dereference freepointer
in slab
- Add CONFIG_STACKDEPOT statement to handle stackdepot
is disable
- Add CONFIG_PAGE_OWNER statement to handle page owner
is disable
- Rebase to linux-next/next-20230808
