If it is just a typo, then it's appears to be a problem where you typedef'd a type, but didn't include the header file for that type.

| yes, that's a typo. I think the error is because of one of these two reasons: 1. the header file for kmem_cache_t is not included: I tried to find the header file but I couldn't. 2. cache_chain is not initialized. this reason is more logical for me, but I don't know how to initialize it. can you help me, please? and, thanks for first reply. |

Then I googled this [PATCH] Remove the deprecated "kmem_cache_t" typedef from slab.h. apparently kmem_cache_t used to be in slab.h (a kernel header) but is no longer used in the kernel tree so has been depreciated right out. I think the original typdef is in that post tho, so you could just paste it in.
