In that case, I usually sprinkle kmsan_che= ck() calls in areas that seem to be relevant, to try and iteratively narrow the problem down to its root cause. I've hit KMSAN issues in NFS before and fi= xed all that I could find. Offset 28 corresponds to st_uid, which is a bit surprising. Can you descri= be your NFS setup a bit? Are you using v3 or v4? What exports flags do you h= ave set? --=20 You are receiving this mail because: You are the assignee for the bug.=
