Recently a 2 year old bug was found in the SLAB allocator that crashes the kernel. This seems to imply that not that many people are using the SLAB allocator. Currently we have 3 slab allocators. Two is company three is a crowd - let's get rid of one. - The SLUB allocator has been the default since 2.6.23 - The SLOB allocator is kinda sexy. Its only 664 LOC, the general design is outlined in KnR, and there is an optimisation taken from Knuth - say no more. If you are using the SLAB allocator please speak now or forever hold your peace ... Testing: Build kernel with `make defconfig` (on x86_64 machine) followed by `make kvmconfig`. Then do the same and manually select SLOB. Boot both kernels in Qemu. thanks, Tobin. Tobin C.
