hello,
Is there any restricition on using
kernel's memory? also if i require to use some kernel
memory say 625kB by allocating that in GFP_ATOMIC mode
Your call will almost certainly fail. I think kmalloc will only give
you up to 128KB, and even that might be tricky to do with GFP_ATOMIC.
For larger chunks of memory, you can use vmalloc() or reserve it
statically at compile time.
