We do have a sysctl "drop_caches" which calls
iterate_supers(drop_pagecache_sb, NULL) and drop_slab().
doc/Documentation/sysctl/vm.txt:
==============================================================
drop_caches
Writing to this will cause the kernel to drop clean caches, as well as
reclaimable slab objects like dentries and inodes. Once dropped, their
memory becomes free....

[PATCH RFC v4 00/13] virtio-mem: paravirtualized memory
This series is based on latest linux-next. The patches are located at:
https://github.com/davidhildenbrand/linux.git virtio-mem-rfc-v4
The basic idea of virtio-mem is to provide a flexible,
cross-architecture memory hot(un)plug solution that avoids many limitations
imposed by existing technologies, architectures, and interfaces. More
details can be found below and in linked material.
