However, I've determined that the corrupti= on in fusefs has a different root cause. And it's more general, too. It can = be triggered by mmap()ing a file, then setting O_DIRECT and doing a write. It doesn't require fspacectl. Going forward, let's restrict this bug to discussion of UFS. --=20 You are receiving this mail because: You are the assignee for the bug.=
