From 363d4251d4bd984c304e0989789f6494343660fd Mon Sep 17 00:00:00 2001 From: Shen Feng Date: Fri, 11 Jul 2008 19:27:31 -0400 Subject: [PATCH] ext4: remove quota allocation when ext4_mb_new_blocks fails Quota allocation is not removed when ext4_mb_new_blocks calls kmem_cache_alloc failed. Also make sure the allocation context is freed on the error path.
