[PATCH 2/9] xfs_repair: remove gratuitous code block in phase5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Eric Sandeen <sandeen@xxxxxxxxxx>

A commit back in 2008 removed a "for" loop ahead of this code block, but
left the indented code block in place. Remove it for clarity and reflow
comments & lines as needed.
