From 0d95326d9bd39f6eae80b91392b308c5fa8b1a0f Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Tue, 22 Mar 2011 13:52:44 -0400 Subject: [PATCH] GFS2: remove *leaf_call_t and simplify leaf_dealloc Since foreach_leaf is only called with leaf_dealloc as its only possible call function, we can simplify the code by making it call leaf_dealloc directly. This simplifies the code and eliminates the need for leaf_call_t, the generic call method. This is a first small step in simplifying the directory leaf deallocation code.
