As the r10_bio comes from a mempool, and the allocation function uses kzalloc it is often zero anyway. But sometimes it isn't and it is best to be safe. I only noticed this because of the bug fixed by an earlier patch where the r10_bios allocated for a reshape were left around to be used by a subsequent resync. In that case the R10BIO_IsReshape flag caused problems. Signed-off-by: NeilBrown --- Reading git-diff-tree failed
