XFS_TRANS_HAS_INTENT_DONE is a flag to the CIL that we've added a log intent done item to the transaction. This enables an optimization wherein we avoid writing out log intent and log intent done items if they would have ended up in the same checkpoint. This reduces writes to the ondisk log and speeds up recovery as a result. However, callers can use the defer ops machinery to modify xattrs without using the log items. In this situation, there won't be an intent done item, so we do not need to set the flag. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Christoph Hellwig <hch@lst.de>
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.
