commit 9994cca22b2c4948c7948f4d83dc3e8efbbd121e
Author: Jeremy Allison <jra at samba.org>
Date: Wed Jun 8 14:38:09 2011 -0700
Part 5 of bugfix for #8211 - "inherit owner = yes" doesn't interact correctly with "inherit permissions = yes" and POSIX ACLs
Ensure when creating a directory, if we make any changes due to inheritance parameters, we update the stat returned.

Part 4 of bugfix for #8211 - "inherit owner = yes" doesn't interact correctly with "inherit permissions = yes" and POSIX ACLs
We don't need to check mode bits as well as dev/ino to
ensure we're in the same place.

Part 3 of bugfix for #8211 - "inherit owner = yes" doesn't interact correctly with "inherit permissions = yes" and POSIX ACLs
When changing ownership on a new file make sure we
must have a valid stat struct before making the inheritance
calls (as they may look at it), and if we make changes we
must have a valid stat struct after them.

When changing ownership on a new file make sure we
also change the returned stat struct to have the correct uid.
