Here is a bugfix to d_path.
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. This is demonstrated by the attached test
case, which prints "getcwd returned d_path-bugsubdir" with the bug. The
correct result would be "getcwd returned d_path-bug/subdir".
It could be argued that the name of the root dentry should not be part of
the result of d_path in the first place. On the other hand, what the
unconnected namespace was once reachable as may provide some useful hints
to users, and so that seems okay.
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.
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(). Grabbing the dcache_lock
can then also be moved into __d_path(). The patch also makes sure that
paths will only start with a slash for paths which are connected to the
root and rootmnt.
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.

Currently, XFS uses BH_PrivateStart for flagging unwritten extent state in a
bufferhead. Recently, I found the long standing mmap/unwritten extent
conversion bug, and it was to do with partial page invalidation not clearing
the unwritten flag from bufferheads attached to the page but beyond EOF. See
here for a full explaination:
http://oss.sgi.com/archives/xfs/2006-12/msg00196.html
The solution I have checked into the XFS dev tree involves duplicating code
from block_invalidatepage to clear the unwritten flag from the bufferhead(s),
and then calling block_invalidatepage() to do the rest.
Christoph suggested that this would be better solved by pushing the unwritten
flag into the common buffer head flags and just adding the call to
discard_buffer():
http://oss.sgi.com/archives/xfs/2006-12/msg00239.html
The following patch makes BH_Unwritten a first class citizen.

This patch contains two fixes for RapisIO enumeration logic:
1. Fix enumeration in configurations with multiple switches. The patch adds:
a. Enumeration of an empty switch. Empty switch is a switch that
does not have any endpoint devices attached to it (except host device
or previous switch in a chain). New code assigns a phony destination
ID associated with the switch and sets up corresponding routes.
b. Adds a second pass to the enumeration to setup routes to
devices discovered after switch was scanned.
2. Fix enumeration failure when riohdid parameter has non-zero value.
Current version fails to setup response path to the host when it has
destination ID other that 0.

If you try to read things like /proc/sys/kernel/osrelease with single-byte
reads, you get just one byte and then EOF. This is because _proc_do_string()
assumes that the caller is read()ing into a buffer which is large enough to
fit the whole string in a single hit.
