You misunderstood. There's two quota _ondisk_ formats: v1 old 16bit quota. v2 new 32bit quota. 2.4 previously only supported v1, 2.5 and 2.4.22-pre4 also support v2. There's three sys_quotactl ABIs 1) original 16 bit one, supported by all kernels <= 2.4 2) first 32bit one, supported by 2.4-ac any many vendor trees, but never in mainline 3) new 32bit one, supported by 2.4.x (x >= 22-pre4) and 2.5 Unfortunately the second one uses the same constants as the old 16bit one but different structures so there is no way to support both in a single kernel. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
