Will be used in the future for inode updates, which will be very helpful for multithreaded workloads that have to update the inode with every extent update (appends, or updates that change i_sectors) Also will be used eventually for fully persistent alloc info However - we still need a mechanism for reserving space in the journal prior to getting a journal reservation, so it's not technically safe to make use of this just yet, we could deadlock with the journal full (although not likely to be an issue in practice) Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
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.
