Subject: [PATCH 1/1] Fix a wrong value passed to __find_vmap_area()
There was a type in the vmalloc_dump_obj() function. Instead
of passing a real address which is "objp" an "addr" was used
what is wrong and not initialized.
Reported-by: kernel test robot <lkp@...el.com>
Fixes: e88b85b81d5 ("mm: vmalloc: offload free_vmap_area_lock lock")
Closes: https://lore.kernel.org/oe-kbuild-all/202401111810.TKPIXLCs-lkp@intel.com/
