Hi, In an application I am freeing some memory address, earlier reserved with malloc. I have put prints in remove_vm_struct() function in ./mm/mmap.c. For few calls to free(), there is no corresponding call to remove_vm_struct(). I am not able to understand why the user space call to free() is not propagated to kernel, where in the remove_vm_strcut() function should get called. Please help.
