Non append, non extending buffered writes can now avoid taking the inode lock. To ensure atomicity of writes w.r.t. other writes, we lock every folio that we'll be writing to, and if this fails we fall back to taking the inode lock. Extensive comments are provided as to corner cases. Link: https://lore.kernel.org/linux-fsdevel/Zdkxfspq3urnrM6I@bombadil.infradead.org/ 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.
