Subject: [PATCH 1/2] cciss: fix sysfs broken symlink regression

Patch 1 of 2

Regression introduced by commit 6ae5ce8e8d4de666f31286808d2285aa6a50fa40.
This patch fixes a broken symlink in sysfs that was introduced by the above
commit also called "cciss: remove redundant code." We broke it in 2.6.27-rc
on or about 20080804. Some installers are broken if this symlink does not
exist and they may not detect the logical drives configured on the
controller.
It does not require being backported into 2.6.26.x or earlier kernels.

Please consider this for inclusion.

Andrew, do I need to resubmit 2 of 2? Or is that one still in your queue?

OK, thanks, I tagged it for 2.6.27.x.

Is this a patch for bug #11404 or for another regression?
