Date: Sun, 28 Feb 2010 20:22:49 -0800 From: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com> To: linux-kernel@...r.kernel.org Cc: zippel@...ux-m68k.org, mingo@...e.hu, akpm@...ux-foundation.org, torvalds@...ux-foundation.org Subject: [PATCH RFC] kconfig: place git SHA1 in .config output if in git tree This patch appends the SHA1 hash of the current git tree to the kernel version line, or "[Not git tree]" if run from a non-git tree. Uses "git log" to print the hash. Suggested-by: Ingo Molnar <mingo@...e.hu> Cc: Roman Zippel <zippel@...ux-m68k.org> Signed-off-by: Paul E.
