From 4d04e4fbf8fc9f5136a64d45e2c20de095c08efb Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Fri, 4 Jul 2008 09:59:34 -0700 Subject: [PATCH] ext4: add missing unlock to an error path in ext4_quota_write() When write in ext4_quota_write() fails, we have to properly release i_mutex. One error path has been missing the unlock...
