From e513182d4d7ec8f1870ae368c549ef2838e2c105 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 28 Apr 2010 12:28:55 +0000 Subject: xfs: report iomap_bn in block base Report the iomap_bn field of struct xfs_iomap in terms of filesystem blocks instead of in terms of bytes. Shift the byte conversions into the caller, and replace the IOMAP_DELAY and IOMAP_HOLE flag checks with checks for HOLESTARTBLOCK and DELAYSTARTBLOCK.
