From ff46d7b3e0870a70331b069372c36fbc43018c2d Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 21 Jul 2008 15:39:05 +0300 Subject: UBIFS: make ubifs_ro_mode() not inline We use ubifs_ro_mode() quite a lot, and not in fast-path, so there is no reason to blow the code up by having it inlined. Also, we usually want R/O mode change to be seen to other CPUs as soon as possible, so when we make this a function call, we will automatically have a memory barrier.

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.
