Hi Alex, Could you please help me to clarify the purpose of init_on_alloc=1 when init_on_free is enabled? If I get it right, init_on_free=1 alone guarantees that the memory returned by the page allocator and SL[AU]B is initialized with zeroes. What is the purpose of init_on_alloc=1 in that case? We are zeroing memory twice, or am I missing something? Thanks a lot! Jirka
