[RFC PATCH 0/4] xfs: add O_TMPFILE support

[Zhi Yong Wu]

From: Zhi Yong Wu <wuzhy at linux.vnet.ibm.com>

HI, folks

The patchset is trying to add O_TMPFILE support to xfs. To make sure
that it is going ahead in the right direction, although it is only one
code draft, and hasn't strictly been tested, it is still post out ASAP.

For more information, please refer to Dave Chinner's RFD links:

Any comments are appreciated, thanks.

Zhi Yong Wu (4):
  xfs: adjust the interface of xfs_qm_vop_dqalloc()
  xfs: add xfs_create_tmpfile() for O_TMPFILE support
  xfs: add a new method xfs_vn_tmpfile()
  xfs: allow linkat() on O_TMPFILE files
