I just run the kprobe.stp test again with strace
strace stap -v -p3 kmodule.stp
The output shows that stap found the ext.ko.debug, but somehow still
can't find the debuginfo
..
.
open("/usr/lib/debug/lib/modules/2.6.9-27.EL/kernel/fs/ext3/ext3.ko.debug",
O_RDONLY|O_LARGEFILE) = 5
fcntl64(5, F_GETFL) = 0x10000 (flags
O_RDONLY|O_LARGEFILE)
fstat64(5, {st_mode=S_IFREG|0644, st_size=2331536, ...}) = 0
mmap2(NULL, 2331536, PROT_READ|PROT_WRITE, MAP_PRIVATE, 5, 0) = 0xf5743000
write(2, "semantic error: ", 16semantic error: ) = 16
write(2, "cannot find module ext3 debuginf"..., 62cannot find module
ext3 debuginfo: Unsupported relocation type) = 62
Could it be a bug in the tranlator, or the debuginfo package is bad?
