[PATCH 20/27] xfs: cleanup the defintion of struct xfs_dir2_data_entry
From: Christoph Hellwig <hch@infradead.org>
Date: 2011-07-01 09:46:07
Remove the tag member which is at a variable offset after the actual name, and make name a real variable sized C99 array instead of the incorrect one-sized array which confuses (not only) gcc.
