[Cluster-devel] [PATCH 34/66] libgfs2: Use dinode buffer to map gfs1 dinode blocks

From: Bob Peterson <rpeterso redhat com>

When function gfs1_block_map found a block for a stuffed file it
wasn't returning the dinode buffer, it was returning the block as a
new buffer.  The problem is, if changes are made to the block, they
will be overwritten by the dinode buffer when that is released.
The result is a fixed block that doesn't get fixed.  This patch
changes the code to return the block properly like gfs2_block_map.
