Subject: [PATCH] xfs: Silence bounds checking compiler warning
Date: Thu, 23 Jun 2011 17:08:22 +0200 [thread overview]
Message-ID: <4E0356E6.30104@gmail.com> (raw)
gcc with -Warray-bounds generates a false positive on this
since xfs defines the struct with u8 name[1]; to be able to
add a tag at the end.
