[openib-general] kernel build failure

[Nishanth Aravamudan]

Hi Roland,

IPOIB is failing to build with 2.6.15 and svn 4981 and 5009

In file included from drivers/infiniband/core/at.c:55:
drivers/infiniband/ulp/ipoib/ipoib.h:52:34: linux/mutex-backport.h: No such file or directory
In file included from drivers/infiniband/core/at.c:55:
drivers/infiniband/ulp/ipoib/ipoib.h:133: error: field `mcast_mutex' has incomplete type
drivers/infiniband/ulp/ipoib/ipoib.h:134: error: field `vlan_mutex' has incomplete type

Is this related the semaphore to mutex conversions from Ingo? If so,
does this mean that it's only expected to build with 2.6.15-git{6,7,...}
or so? (Remember, I'm stuck with 2.6.15 until 2.6.16-rc1 comes out so
that I can use ISER without having to patch again).

Thanks,
Nish
