Sorry, was off on leave.
Hmm, Lucas intimated that kmod version 11 started passing this flag
correctly.
In fact, kmod's modprobe *never* used the O_NONBLOCK
(ie. KMOD_REMOVE_NOWAIT) flag, until it was finally enforced in
commit 7ab8804448377fb6b8854f2dd288608db01bb43b

See: tools/modprobe.c at that commit:
static int rmmod_do_remove_module(struct kmod_module *mod)
{
const char *modname = kmod_module_get_name(mod);
struct kmod_list *deps, *itr;
int flags = 0, err;
...
if (force)
flags |= KMOD_REMOVE_FORCE;
err = kmod_module_remove_module(mod, flags);
Perhaps we need to just get rid of the kernel message, since we're
getting far too many false reports :(
Cheers,
Rusty.
