+Subject: ubifs: Add missing iput if do_tmpfile() failed in rename whiteout
+
+From: Zhihao Cheng <chengzhihao1@huawei.com>
+
+commit 716b4573026bcbfa7b58ed19fe15554bac66b082 upstream.
+
+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")

+Subject: ubifs: setflags: Make dirtied_ino_d 8 bytes aligned
+
+From: Zhihao Cheng <chengzhihao1@huawei.com>
+
+commit 1b83ec057db16b4d0697dc21ef7a9743b6041f72 upstream.
+
+Make 'ui->data_len' aligned with 8 bytes before it is assigned to
+dirtied_ino_d. Since 8871d84c8f8b0c6b("ubifs: convert to fileattr")
+applied, 'setflags()' only affects regular files and directories, only
+xattr inode, symlink inode and special inode(pipe/char_dev/block_dev)
+have none- zero 'ui->data_len' field, so assertion
+'!(req->dirtied_ino_d & 7)' cannot fail in ubifs_budget_space().
+To avoid assertion fails in future evolution(eg. setflags can operate
+special inodes), it's better to make dirtied_ino_d 8 bytes aligned,
+after all aligned size is still zero for regular files.
