Subject: max_user_watches overflows on 16TB system.
Date: Fri, 1 Oct 2010 15:01:43 -0500	[thread overview]
Message-ID: <20101001200143.GR14064@sgi.com> (raw)


Following a boot of a 16TB system, we noticed that the max_user_watches
sysctl was negative.  Is there any downside to converting that to a
static long and handling the fallout from the change?  I believe that
fallout includes changing the definition of epoll_watches over to an
atomic_long_t as well.

Alternatively should we just limit max_user_watches to INT_MAX?

Thanks,
Robin Holt
