Zhi Yong Wu	99b6436bc2	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().

Dave Chinner	70a9883c5f	xfs: create a shared header file for format-related information ... All of the buffer operations structures are needed to be exported for xfs_db, so move them all to a common location rather than spreading them all over the place. They are verifying the on-disk format, so while xfs_format.h might be a good place, it is not part of the on disk format. Hence we need to create a new header file that we centralise these related definitions. Start by moving the bffer operations structures, and then also move all the other definitions that have crept into xfs_log_format.h and xfs_format.h as there was no other shared header file to put them in.
