From 0c2022eccb01630c037f2024531e9ff1afbe1564 Mon Sep 17 00:00:00 2001 From: Yongqiang Yang Date: Mon, 20 Feb 2012 17:53:02 -0500 Subject: jbd2: allocate transaction from separate slab cache There is normally only a handful of these active at any one time, but putting them in a separate slab cache makes debugging memory corruption problems easier. Manish Katiyar also wanted this make it easier to test memory failure scenarios in the jbd2 layer.
