(Fixed in KEDR 0.4) KEDR fails to build for kernel 3.3.0 #5

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When building KEDR 0.3 on the Linux kernel 3.3.0, compilation fails with the 
following error:

------------------

------------------

It seems that the signature of __init_waitqueue_head changed in the kernel 
3.3.0:

void __init_waitqueue_head(wait_queue_head_t *q, const char *name, struct 
lock_class_key *key)

In the kernel 3.2.x and earlier, it has no 'name' argument:
void __init_waitqueue_head(wait_queue_head_t *q, struct lock_class_key *key)

The problem seems to affect call tracing facilities only. If they are not used, 
one can disable them when configuring KEDR, as a temporary workaround:

cmake -DKEDR_STANDARD_CALLM_PAYLOADS=off \
    <other_options_if_needed> <path_to_kedr_source_tree>
