Hello -
Clang reports a possible user of an uninitalized variable in
nfs_vnops.c line 2605.
attrflag is uninitialized when calling nfsm_postop_attr(), which is a
macro that only sets attrflag if (info.nmi_mrep != NULL). I am not sure
if that is possible, but maybe a KASSERT(info.nmi_mrep != NULL) before
nfsm_postop_attr() would catch a bug...
Or just silence it with:
