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 fr= ee memory indicated by=A0kmem_map_free goes down, and this is=A0proportiona= l=A0to the size of the data written. However, even after removing all the d= ata,=A0kmem_map_free doesn't seem to go up. Its only after detaching the me= mory disk does the free memory go up. May I know the reason for this behavi= or?=A0 Thanks,-shrivatsan=0A=0A=0A
