Joel Fernandes (Google) 1f55e7667a mm/vmalloc: add a safer version of find_vm_area() for debug ... commit 0818e739b5 upstream. It is unsafe to dump vmalloc area information when trying to do so from some contexts. Add a safer trylock version of the same function to do a best-effort VMA finding and use it from vmalloc_dump_obj(). [applied test robot feedback on unused function fix.] [applied Uladzislau feedback on locking.] Link: https://lkml.kernel.org/r/20230904180806.1002832-1-joel@joelfernandes.org Fixes: 98f180837a ("mm: Make mem_dump_obj() handle vmalloc() memory") Signed-off-by: Joel Fernandes (Google) <joel@joelfernandes.org> Reviewed-by: Uladzislau Rezki (Sony) <urezki@gmail.com> Reported-by: Zhen Lei <thunder.leizhen@huaweicloud.com> Cc: Paul E.
