Perhaps...
But, as I said, I think that until we fix the callers uprobe_mmap()
should ignore all errors and proceed. Except, perhaps, it makes sense
to check fatal_signal_pending() to not upset oom-killer.
I already had this patch, but then I decided it would be better to
do other changes first. See my next reply to your another email.
Oleg.
