Transaction reservation overrun detection currently occurs too late to print useful information about the offending transaction. Ideally, the transaction data is printed before the associated log items are moved from the transaction to the CIL, which occurs in xlog_cil_insert_items(), such that details of the items logged by the transaction are available for analysis. Refactor xlog_cil_insert_items() to facilitate moving tx overrun detection to this function. Update the function to track each bit of extra log reservation stolen from the transaction (i.e., such as for the CIL context ticket) and perform the log item migration as the last operation before the CIL lock is released. This creates a context where the transaction reservation consumption has been fully calculated when the log items are moved to the CIL. This patch makes no functional changes.

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.
