From b364b41aeb0289be402be83eebca92eb90bfcb8b Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Fri, 25 Jul 2008 14:38:51 +0300 Subject: UBIFS: reserve more space for index At the moment UBIFS reserves twice old index size space for the index. But this is not enough in some cases, because if the indexing node are very fragmented and there are many small gaps, while the dirty index has big znodes - in-the-gaps method would fail. Thus, reserve trise as more, in which case we are guaranteed that we can commit in any case.
