Subject: GFS2: Get a block reservation before resizing a file
From: Bob Peterson <[email protected]>
commit d2b47cfb26fe06002b8011707baac71a9ae8166f upstream.
This patch allocates a block reservation structure before growing
or shrinking a file. Without this structure, the grow or shink code
can reference the bad pointer.
