Currently, the transaction complete work item is queued after the transaction. This means that it is possible for the transaction to be handled and a reply to be enqueued in the current thread before the transaction complete is enqueued, which violates the protocol with userspace who may not expect the transaction complete. Fixed by always enqueing the transaction complete first. Also, once the transaction is enqueued, it is unsafe to access since it might be freed. Currently, t->flags is accessed to determine whether a sync wake is needed. Changed to access tr->flags instead.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
