Hello, I tried to allocate (vmalloc) huge (512MB) memory block inside my init_module(), but without success. It is possible to get about 48MB only. I work on Pentium SMP, 1GB RAM, RedHat-6.2 with kernel 2.2.18. Is there some restrictions on vmalloc'ed size? I need non-swapped memory block, of course. Thank you in advance!
