[ewg] [RFC] OFED-3.2 kernel development

[Steve Wise]

Hey vlad,  I ran the admin_rdma.sh script and it logged a few fatal errors:

fatal: No annotated tags can describe '6343adaefb8a7a21d9ae1a018159f90f482cac61'.
However, there were unannotated tags: try --tags.
Updated from local tree: /tmp/git/linux-3.2/
Origin remote URL: git://git.openfabrics.org/compat-rdma/linux-3.2.git
fatal: No names found, cannot describe anything.


Is this expected?
