From f1dbcd7e38c80c2165516b4432231b46f1adc76c Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Thu, 27 Feb 2014 15:18:23 +1100 Subject: xfs: add helper for updating checksums on xfs_bufs Many/most callers of xfs_update_cksum() pass bp->b_addr and BBTOB(bp->b_length) as the first 2 args. Add a helper which can just accept the bp and the crc offset, and work it out on its own, for brevity.
