This more or less restores the state before commit 34fa110e. The commit message there explains that s->discard_zeroes is unreliable (in particular, it is false on block devices on recent kernels even though they may support zeroing by discard just fine). We should instead remove s->discard_zeroes because it is currently unused. I'll send a patch. Kevin
