How about introducing a tiny inline function which returns either EBUSY
or ESTALE?
static inline int busy_or_stale()
{
if (!test_distributed_fs())
return -EBUSY;
return -ESTALE;
}
For nfs, the test function will be something like this.
int test_nfsd()
{
int ret;
struct task_struct *tsk = current;
char comm[sizeof(tsk->comm)];
ret = 0;
if (tsk->flags & PF_KTHREAD) {
get_task_comm(comm, tsk);
ret = !strcmp(comm, "nfsd");
}
return ret;
}
I know this "by-name" test is not good.
