The xlog_write() function iterates over iclogs until it completes writing all the log vectors passed in. The ticket tracks whether a start record has been written or not, so only the first iclog gets a start record. We only ever pass single use tickets to xlog_write() so we only ever need to write a start record once per xlog_write() call. Hence we don't need to store whether we should write a start record in the ticket as the callers provide all the information we need to determine if a start record should be written. For the moment, we have to ensure that we clear the XLOG_TIC_INITED appropriately so the code in xfs_log_done() still works correctly for committing transactions. (darrick: Note the slight behavior change that we always deduct the size of the op header from the ticket, even for unmount records) Signed-off-by: Dave Chinner <dchinner@redhat.com> [hch: pass an explicit need_start_rec argument] Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Darrick J.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
