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.

Creating, renaming or deleting a file may hit BUG_ON() if the first
record of both a leaf node and its parent are changed, and if this
forces the parent to be split. This bug is triggered by xfstests
generic/027, somewhat rarely; here is a more reliable reproducer:
truncate -s 50M fs.iso
mkfs.hfsplus fs.iso
mount fs.iso /mnt
i=1000
while [ $i -le 2400 ]; do
touch /mnt/$i &>/dev/null
((++i))
done
i=2400
while [ $i -ge 1000 ]; do
mv /mnt/$i /mnt/$(perl -e "print $i x61") &>/dev/null
((--i))
done
The issue is that a newly created bnode is being put twice. Reset
new_node to NULL in hfs_brec_update_parent() before reaching goto again.
