2014-03-13Merge branch 'xfs-O_TMPFILE-support' into for-nextDave Chinner
Conflicts: fs/xfs/xfs_trans_resv.c - fix for XFS_INODE_CLUSTER_SIZE macro removal
2014-02-07xfs: remove unused tr_swriteEric Sandeen
tr_swrite is never used, remove it. From a very quick look, I think the usage of it (and its ancestor XFS_SWRITE_LOG_RES) went away in commit 13e6d5cd "xfs: merge fsync and O_SYNC handling" back in 2009.

2014-01-06xfs: add O_TMPFILE supportZhi Yong Wu
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().

2013-08-12xfs: refactor xfs_trans_reserve() interfaceJie Liu
With the new xfs_trans_res structure has been introduced, the log reservation size, log count as well as log flags are pre-initialized at mount time. So it's time to refine xfs_trans_reserve() interface to be more neat. Also, introduce a new helper M_RES() to return a pointer to the mp->m_resv structure to simplify the input.

2013-08-12xfs: Make writeid transaction use tr_writeidJie Liu
tr_writeid is defined at mp->m_resv structure, however, it does not really being used when it should be.. This patch changes it to tr_writeid to fetch the correct log reservation size.

2013-08-12xfs: Introduce tr_fsyncts to m_reservationJie Liu
A preparation step. For now fsync_ts transaction use the pre-calculated log reservation size of tr_swrite. This patch introduce a new item tr_fsyncts to mp->m_reservations structure so that we can fetch the log reservation value for it in a same manner to others.

2013-08-12xfs: Introduce a new structure to hold transaction reservation itemsJie Liu
Introduce a new structure xfs_trans_res to hold transaction reservation item info per log ticket. We also need to improve xfs_trans_resv_calc() by initializing the log count as well as log flags for permanent log reservation.

2013-08-12xfs: split out transaction reservation codeDave Chinner
The transaction reservation size calculations is used by both kernel and userspace, but most of the transaction code in xfs_trans.c is kernel specific. Split all the transaction reservation code out into it's own files to make sharing with userspace simpler. This just leaves kernel-only definitions in xfs_trans.h, so it doesn't need to be shared with userspace anymore, either.
