From 2f5beb4b530d47d6b4a7cf0effeaec0d2c1b6ea4 Mon Sep 17 00:00:00 2001 From: Luca Barbieri Date: Tue, 23 Feb 2010 08:55:24 -0800 Subject: [PATCH] pipebuffer: slab: if size < alignment, use alignment to find bucket MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If the size is lower than the alignment, we must use the alignment to select the bucket. Otherwise, the selected bucket won't be able to satisfy our request and will fail.
