Bob Peterson 39b0f1e929 GFS2: Don't brelse rgrp buffer_heads every allocation ... This patch allows the block allocation code to retain the buffers for the resource groups so they don't need to be re-read from buffer cache with every request. This is a performance improvement that's especially noticeable when resource groups are very large. For example, with 2GB resource groups and 4K blocks, there can be 33 blocks for every resource group. This patch allows those 33 buffers to be kept around and not read in and thrown away with every operation. The buffers are released when the resource group is either synced or invalidated.
