In 2022 the SLOB allocator was deprecated and removed with Linux 6.4 a year later. SLOB was popular with embedded systems with minimal amounts of RAM, so as a result the CONFIG_SLUB_TINY Kconfig option was then added for configuring the slab allocator for a minimal memory footprint for systems with 16MB of RAM or less. The CONFIG_SLUB_TINY is now on the chopping block with a proposed rework to the allocator code for making the "tiny" memory handling a boot time option.
