From 8f04c47aa9712874af2c8816c2ca2a332cba80e4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 8 Jul 2011 14:34:34 +0200 Subject: [PATCH] xfs: split xfs_itruncate_finish Split the guts of xfs_itruncate_finish that loop over the existing extents and calls xfs_bunmapi on them into a new helper, xfs_itruncate_externs. Make xfs_attr_inactive call it directly instead of xfs_itruncate_finish, which allows to simplify the latter a lot, by only letting it deal with the data fork. As a result xfs_itruncate_finish is renamed to xfs_itruncate_data to make its use case more obvious. Also remove the sync parameter from xfs_itruncate_data, which has been unessecary since the introduction of the busy extent list in 2002, and completely dead code since 2003 when the XFS_BMAPI_ASYNC parameter was made a no-op. I can't actually see why the xfs_attr_inactive needs to set the transaction sync, but let's keep this patch simple and without changes in behaviour. Also avoid passing a useless argument to xfs_isize_check, and make it private to xfs_inode.c.
