From 99b6436bc29e4f10e4388c27a3e4810191cc4788 Mon Sep 17 00:00:00 2001 From: Zhi Yong Wu Date: Wed, 18 Dec 2013 08:22:40 +0800 Subject: [PATCH] xfs: add O_TMPFILE support Add two functions xfs_create_tmpfile() and xfs_vn_tmpfile() to support O_TMPFILE file creation. In contrast to xfs_create(), xfs_create_tmpfile() has a different log reservation to the regular file creation because there is no directory modification, and doesn't check if an entry can be added to the directory, but the reservation quotas is required appropriately, and finally its inode is added to the unlinked list. xfs_vn_tmpfile() add one O_TMPFILE method to VFS interface and directly invoke xfs_create_tmpfile().
