From 61436febae29085bffc7c291db03cbd709dc68a3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 20 May 2008 11:30:46 +1000 Subject: [XFS] kill xfs_igrow_start and xfs_igrow_finish xfs_igrow_start just expands to xfs_zero_eof with two asserts that are useless in the context of the only caller and some rather confusing comments. xfs_igrow_finish is just a few lines of code decorated again with useless asserts and confusing comments. Just kill those two and merge them into xfs_setattr.
