Hi all, This set is a subset of a larger series parent pointers. Delayed attributes allow attribute operations (set and remove) to be logged and committed in the same way that other delayed operations do. This allows more complex operations (like parent pointers) to be broken up into multiple smaller transactions. To do this, the existing attr operations must be modified to operate as a delayed operation. This means that they cannot roll, commit, or finish transactions. Instead, they return -EAGAIN to allow the calling function to handle the transaction. In this series, we focus on only the delayed attribute portion. We will introduce parent pointers in a later set. The set as a whole is a bit much to digest at once, so I usually send out the smaller sub series to reduce reviewer burn out. But the entire extended series is visible through the included github links. Updates since v28: xfs: Set up infrastructure for log attribute replay Fixed xfs_attri_init to initialize shadow buffers for name/value xfs: Implement attr logging and replay Updated calls to xfs_attri_init This series can be viewed on github here: https://github.com/allisonhenderson/xfs_work/tree/delayed_attrs_v29 As well as the extended delayed attribute and parent pointer series: https://github.com/allisonhenderson/xfs_work/tree/delayed_attrs_v29_extended Thanks all!
