From adam@yggdrasil.com Fri Feb 16 05:39:47 2007 From: "Adam J. Richter" Date: Fri, 16 Feb 2007 21:35:25 +0800 Subject: sysfs: move struct sysfs_dirent to private header To: gregkh@suse.de Cc: linux-kernel@vger.kernel.org Message-ID: <20070216213525.A9567@freya> Content-Disposition: inline From: "Adam J. Richter" struct sysfs_dirent is private to the fs/sysfs/ subtree. It is not even referenced as an opaque structure outside of that subtree. The following patch moves the declaration from include/linux/sysfs.h to fs/sysfs/sysfs.h, making it clearer that nothing else in the kernel dereferences it. I have been running this patch for years. Please integrate and forward upstream if there are no objections. From: "Adam J.
