Subject: [PATCH] Btrfs: fix inode leak on kmalloc failure in tree-log.c
Date: Sun, 4 Aug 2013 19:58:57 +0100 [thread overview]
Message-ID: <1375642737-18448-1-git-send-email-fdmanana@gmail.com> (raw)
In tree-log.c:replay_one_name(), if memory allocation for
the name fails, ensure we iput the dir inode we got before
before we return.
