Z3fold & Zbud Allocators Likely To Be Removed In Linux 6.15
It's looking like Linux 6.15 will be the kernel that does away with the Z3fold and Zbud allocators.
It shouldn't be too surprising given that these compressed page allocators were already deprecated and slated for removal. Zsmalloc used to have worse latency than Zbud/Z3fold but that is no longer the case and these deprecated allocators consume much more memory. Unless any good reasons come up for keeping the roughly two thousand lines of code around, they are expected to be dropped during the Linux 6.15 merge window.
