From ae24f28d39610a4810c78185cf599a771cf6ee1f Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 25 May 2011 17:39:48 -0400 Subject: [PATCH] ext4: Convert ext4 to new truncate calling convention Trivial conversion. Fixup one error handling case calling vmtruncate() and remove ->truncate callback. We also fix a bug that IS_IMMUTABLE and IS_APPEND files could not be truncated during failed writes. In fact, the test can be completely removed as upper layers do necessary permission checks for truncate in do_sys_[f]truncate() and may_open() anyway.
