Subject: [PATCH v2 04/12] ubifs: Add missing iput if do_tmpfile() failed in rename whiteout
Date: Sat, 6 Nov 2021 20:25:09 +0800	[thread overview]
Message-ID: <20211106122517.3304628-5-chengzhihao1@huawei.com> (raw)
In-Reply-To: <20211106122517.3304628-1-chengzhihao1@huawei.com>

whiteout inode should be put when do_tmpfile() failed if inode has been
initialized. Otherwise we will get following warning during umount:
  UBIFS error (ubi0:0 pid 1494): ubifs_assert_failed [ubifs]: UBIFS
  assert failed: c->bi.dd_growth == 0, in fs/ubifs/super.c:1930
  VFS: Busy inodes after unmount of ubifs. Self-destruct in 5 seconds.

Fixes: 9e0a1fff8db56ea ("ubifs: Implement RENAME_WHITEOUT")
