Re: [Cluster-devel] [PATCH 4 of 5]Bz #248176: GFS2: invalid metadata block - RESEND



Hi,

I've pushed patches 1-3, patches 4 & 5 don't apply. It looks like a path
problem. You need to generate the patches so that they can be applied
with patch -p1 from the top level of the source tree (so the best way is
by being one level up from that when you run diff),

Steve.
