From b1967d0eddeef4869ee283e692735cb994f3745a Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Tue, 20 Nov 2007 11:56:39 -0800 Subject: [PATCH] ocfs2: reverse inline-data truncate args ocfs2_truncate() and ocfs2_remove_inode_range() had reversed their "set i_size" arguments to ocfs2_truncate_inline(). Fix things so that truncate sets i_size, and punching a hole ignores it. This exposed a problem where punching a hole in an inline-data file wasn't updating the page cache, so fix that too.
