The commit: f3edb66a mkfs.xfs: validate options for CRCs up front. unintentionally (?) defaulted to projid32bit=1 for all filesystems at mkfs time. Support for 32 bit project IDs has been present since kernel v2.6.37. Is everybody ok with making this change for 3.2.0? Speak now or forever hold your peace, as they say. -Eric
