Linux kernel source tree

Kuniyuki Iwashima says: ==================== phonet: Convert all doit() and dumpit() to RCU. addr_doit() and route_doit() access only phonet_device_list(dev_net(dev)) and phonet_pernet(dev_net(dev))->routes, respectively. Each per-netns struct has its dedicated mutex, and RTNL also protects the structs. __dev_change_net_namespace() has synchronize_net(), so we have two options to convert addr_doit() and route_doit(). 1. Use per-netns RTNL 2. Use RCU and convert each struct mutex to spinlock_t As RCU is preferable, this series converts all PF_PHONET's doit() and dumpit() to RCU. 4 doit()s and 1 dumpit() are now converted to RCU, 70 doit()s and 28 dumpit()s are still under RTNL. ==================== Link: https://patch.msgid.link/20241017183140.43028-1-kuniyu@amazon.com Signed-off-by: Paolo Abeni <pabeni@redhat.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 reStructuredText 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.
