From 673e8e597c06eb81954bf21a10f5cce74a1de8f1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 18 Dec 2011 20:00:04 +0000 Subject: xfs: remove xfs_itruncate_data This wrapper isn't overly useful, not to say rather confusing. Around the call to xfs_itruncate_extents it does: - add tracing - add a few asserts in debug builds - conditionally update the inode size in two places - log the inode Both the tracing and the inode logging can be moved to xfs_itruncate_extents as they are useful for the attribute fork as well - in fact the attr code already does an equivalent xfs_trans_log_inode call just after calling xfs_itruncate_extents. The conditional size updates are a mess, and there was no reason to do them in two places anyway, as the first one was conditional on the inode having extents - but without extents we xfs_itruncate_extents would be a no-op and the placement wouldn't matter anyway. Instead move the size assignments and the asserts that make sense to the callers that want it. As a side effect of this clean up xfs_setattr_size by introducing variables for the old and new inode size, and moving the size updates into a common place.
