Subject: [PATCH] fix XFSQA 144
Date: Sat, 14 Jun 2008 21:22:48 +0200	[thread overview]
Message-ID: <20080614192248.GA24329@lst.de> (raw)

Two really dumb bugs:

 - "foo & 0x3FFFFFFFFFFFF" doesn't cap at 1TB, but rather at more than
   two magnitudes larger than that.  That gets us EFBIG with typical
   32bit XFS setups.
 - the command array can easily overflow and thus let the test fail
