Similar concepts are used for raid 6 parity (LSFR + Galois Fields). A pdf I found describing raid 6 parity describes the field and LSFR use and some background. https://www.kernel.org/pub/linux/kernel/people/hpa/raid6.pdf

(I took at stab at implementing them awhile back as an experiment. https://github.com/jimktrains/r6parity)
