It isn't, but I hadn't changed the sources, .config or build environment since I built it, so I did a straight recompile with CONFIG_DEBUG_INFO set, and got: (gdb) l *(isolate_lru_pages+74) 0xffffffff80250c2a is in isolate_lru_pages (list.h:154). (I had to run gdb on a machine with 64-bit userspace, but I guess just copying the vmlinux file should suffice.) /* Steinar */ -- Homepage: http://www.sesse.net/
