"Good operating system performance depends in part on the operating system's ability to efficiently manage resources. In the old days, heap memory managers were the norm, but performance suffered due to fragmentation and the need for memory reclamation. Today, the Linux kernel uses a method that originated in Solaris but has been used in embedded systems for quite some time, allocating memory as objects based on their size. This article explores the ideas behind the slab allocator and examines its interfaces and their use."

It was designed by Jeff Bonwick, the same guy behind ZFS, for Solaris. Later, the design was copied into Linux.

Later, the design was copied into Linux.
And later still, copied into AmigaOS 4. ;-)

"The slab allocator used in Linux is based on an algorithm first introduced by Jeff Bonwick for the SunOS operating system." sounds like a good defence; just in case Microsoft decide to patent "algorithms for allocating memory in slabs"
Everyone better start to track the lineage of their software.
