Linux kernel source tree
fb924b7b86
We only need it when mount in question was sending events downstream (then
recepients need to switch to new master) or the mount is being turned into
slave (then we need a new master for it).
That wouldn't be a big deal, except that it causes quite a bit of work
when umount_tree() is taking a large peer group out. Adding a trivial
"don't bother calling propagation_source() unless we are going to use
its results" logics improves the things quite a bit.
We are still doing unnecessary work on bulk removals from propagation graph,
but the full solution for that will have to wait for the next merge window.

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.
