From 5803c6f8a2faf8cfbbd046d9ebd682b82bb2b086 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 5 Mar 2008 19:44:06 -0800 Subject: Add return value to 'traverse_tree()' callback This allows the callback to return an error value, but it can also specify which of the tree entries that it actually used up by returning a positive mask value.
