Subject: [PATCH 2/5] xfs: adjust the interface of xfs_qm_vop_dqalloc()
From: Zhi Yong Wu <wuzhy@...ux.vnet.ibm.com>
There may be not a parent inode or a name for O_TMPFILE support, but will pass
a struct xfs_mount to xfs_qm_vop_dqalloc(). So its interface need to be
adjusted in order that O_TMPFILE creation function can also use it.
