Re: [EXT4 set 5][PATCH 1/1] expand inode i_extra_isize to support features in larger inode

[Andy Whitcroft <apw@shadowen.org>]

The next version of checkpatch.pl (0.08) should have support for a
number of the missed sylistics you mention.  Will let them soak for a
bit to ensure we're not majorly regressing anything else.
