Probably in a README?

FIFO channel should support a number of commands for each error injection: - errinj_errno - errinj_kill_caller - errinj_noop - behavior is undefined - errinj_slowdown

unreliablefs uses linked list for error injections, see https://github.com/ligurio/unreliablefs/blob/c6a6b1e7136de3ff25dacf2cf785406313a6b39f/unreliablefs_errinj.c#L183-L235 On each operation, it traverses a list with error injections, and it is not optimal from performance point of view, algorithmic...
