Hi all, This set is a subset of a larger series for delayed attributes. Which is a subset of an even 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 either a delayed operation or a inline operation since older filesystems will not be able to use the new log entries. This means that they cannot roll, commit, or finish transactions. Instead, they return EAGAIN an allow the calling function to handle the transaction. In this series, we focus on only the clean up and refactoring needed to accomplish this. We will introduce delayed attrs and parent pointers in a later set. Changes since v3: Mostly review updates collected since v3. Patches 15, 16, and 17 are new and apply most of the new code flow changes. No new function is added at this time. I've also made the corresponding updates to the user space side, and xfstests as well. Question, comment and feedback appreciated! Thanks all!
