[rsbac] bug in rsbac_kmalloc() ?

[Michal Purzynski]

hello

looking at rsbac_kmalloc() implementation, i see that memory in case of 2.6 kernel is allocated like this:

kmem_cache_alloc(csizep->cs_cachep, 0)

so flags are `0`. i think it is bad - with preempt turned on flags should be GFP_ATOMIC. now with `0` flags rsbac_kmalloc() is allowed to sleep, what can lead to `bad: scheduling while atomic` errors in case of allocating memory between spinlocks.

i am going to test it with GFP_ATOMIC, and will tell about results.
