Hi hackers,
I have configured a malloc-backed memory disk, and I mount the device on to the 
file system. I write some data onto the file system. I see that the free memory 
indicated by kmem_map_free goes down, and this is proportional to the size of 
the data written. However, even after removing all the data, kmem_map_free 
doesn't seem to go up. Its only after detaching the memory disk does the free 
memory go up. May I know the reason for this behavior? 

Thanks,-shrivatsan
