-Index: linux-2.6/fs/dcache.c
+Fix __d_path() for lazy unmounts and make it unambiguous
+
+First, when d_path() hits a lazily unmounted mount point, it tries to
+prepend the name of the lazily unmounted dentry to the path name. It
+gets this wrong, and also overwrites the slash that separates the name
+from the following pathname component.
+
+Second, it isn't always possible to tell from the __d_path result
+whether the specified root and rootmnt (i.e., the chroot) was reached:
+lazy unmounts of bind mounts will produce a path that does start with a
+non-slash so we can tell from that, but other lazy unmounts will produce
+a path that starts with a slash, just like "ordinary" paths.
+
+Third, sys_getcwd() shouldn't return disconnected paths. The patch
+checks for that, and makes it fail with -ENOENT in that case.
+
+The attached patch cleans up __d_path() to fix the bug with overlapping
+pathname components. It also adds a @fail_deleted argument, which allows
+to get rid of some of the mess in sys_getcwd(). We make sure that paths
+will only start with a slash if the path leads all the way up to the
+root. If the resulting path would otherwise be empty, we return "."
+instead so that some users of seq_path for files in /proc won't break.
+
+The @fail_deleted argument allows sys_getcwd() to be simplified.
+Grabbing the dcache_lock can be moved into __d_path().
+
+The @fail_deleted argument could be added to d_path() as well: this would
+allow callers to recognize deleted files without having to resort to the
+ambiguous check for the " (deleted)" string at the end of the pathnames.
+This is not currently done, but it might be worthwhile.

+Hide unreachable mount points in /proc/mounts and /proc/$PID/mountstats
+
+What's mounted on unreachable mount points isn't interesting to
+processes: they can't get there in the first place. This patch hides
+unreachable mounts from processes.
+
+Processes living in the root namespace whill still see all mounts they
+were seeing before except for the rootfs mount, which is never reachable
+from an "ordinary" process.
+
+Only the initial initrd init process will actually have access to the
+rootfs mount. For this process that mount *is* reachable, and so it will
+show in.
+
+This patch also removes some code duplication between mounts_open() and
+mountstats_open().
