From: Christoph Hellwig <hch@xxxxxx> Use mp->m_sb.sb_rblocks to calculate the end instead of sb_rextents that needs a conversion, use consistent names to xfs_rtblock_t types, and only calculated them by the time they are needed. Remove the pointless "high" local variable that only has a single user. Signed-off-by: Christoph Hellwig <hch@xxxxxx> Reviewed-by: Darrick J. Wong <djwong@xxxxxxxxxx> Signed-off-by: Darrick J.
