It made sense to have the global reserve set at 16M in the past, but since it is used less nowadays set the minimum size to the number of items we'll need to update the main trees we update during a transaction commit, plus some slop area so we can do unlinks if we need to. In practice this doesn't affect normal file systems, but for xfstests where we do things like fill up a fs and then rm * it can fall over in weird ways. This enables us for more sane behavior at extremely small file system sizes. Signed-off-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: David Sterba <dsterba@suse.com>
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.
