scheduling in kmalloc()

if we use any thing other than GFP_ATOMIC, does it result in scheduling out the process if there is no memory available?
with GFP_KERNRL, I think we try freeing pages to service the current request.
or is there any possibility of kmalloc() failing even with GFP_KERNEL?

thx,
Vasu.

kmalloc can always fail, looping on a kmalloc at high level can almost always cause deadlocks so you need to be prepared to fail
