Subject: [patch 3/5] x86: headers cleanup - ptrace-abi.h
Date: Wed, 14 Jan 2009 23:37:48 +0300 [thread overview]
Message-ID: <496e4e23.0c07560a.5e4e.529c@mx.google.com> (raw)
In-Reply-To: <20090114203745.285473388@gmail.com>

Impact: cleanup
'make headers_check' warn us about leaking of kernel private
(mostly compile time vars) data to userspace in headers. Fix it.
ptrace_bts_config struct is wrapped by __KERNEL__ --
not sure if it was ever proposed for userland. On the
other hand branch tracing is really anxious for userland
developers.
