Subject: [patch] enable wchan config menu item for x86-64
Date: Thu, 6 Nov 2008 11:10:49 -0800	[thread overview]
Message-ID: <b040c32a0811061110g69b6cc6cta88774b72e5b9163@mail.gmail.com> (raw)

Ingo,

I don't know when will you phase out /proc/pid/wchan.  Can we enable the
wchan config menu item for now on x86-64 arch?  This will at least allow
people to enable/disable frame pointers on scheduler functions.
