From c2774d84fd6cab2bfa2a2fae0b1ca8d8ebde48a2 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Fri, 10 Oct 2008 20:07:20 -0400 Subject: [PATCH] ext4: Do mballoc init before doing filesystem recovery During filesystem recovery we may be doing a truncate which expects some of the mballoc data structures to be initialized. So do ext4_mb_init before recovery.
