Wong" Message-ID: <1486022171-8076-16-git-send-email-hch@lst.de> From: "Darrick J. Wong" commit 83d230eb5c638949350f4761acdfc0af5cb1bc00 upstream. sb_dirblklog is added to sb_blocklog to compute the directory block size in bytes. Therefore, we must compare the sum of both those values against XFS_MAX_BLOCKSIZE_LOG, not just dirblklog. Signed-off-by: Darrick J.
