From a6849fa1f7d7d7adbeb6a696beeabfa078acf173 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Mon, 20 Sep 2010 00:56:27 -0700 Subject: [PATCH] sysfs: Fail bin file mmap if vma close is implemented. It is not reasonably possible to wrap vma->close(). To correctly wrap close would imply calling close on any vmas that remain when sysfs_remove_bin_file is called. Finding the proper lists walking them getting the locking right etc, requires deep knowledge of the mm subsystem and as such would require assistence from the mm subsystem to implement. That assistence does not currently exist. Signed-off-by: Eric W. Biederman Signed-off-by: Greg Kroah-Hartman --- Reading git-format-patch failed
