Hello,
I get a segfault when i try to insmod a module that
calls kmem_cache_create. Here is the 'relevent' code:
node_cache =
kmem_cache_create ("hash_table_nodes_cache",
sizeof (HashTableNode),
0, SLAB_HWCACHE_ALIGN, NULL, NULL);
the value of sizeof (HashTableNode) is 16.
Here is the exact error i get:
------------[ cut here ]------------
