SubjectRe: patch: reiserfs for 2.3.49
Thanks much Rask.  Alexander, look into this, and try running make config on a
kernel tree stored in reiserfs for your 2.3.51 patch. If you can compile the
kernel on your 2.3.51 port patch then send Rask your 2.3.51 patch to see if what
he found is a bug for that version also. Note that Rask is using md.

(Thanks to Alexander we now have a 2.3.51 patch that has passed a few initial
tests, and needs more testing.)
