max_vfs is a strange little beast because the file hangs off of nsim's debugfs, but it configures a field in the bus device. Move it to dev.c, let's look at it as if the device driver was imposing VF limit based on FW info (like pci_sriov_set_totalvfs()). Again, when moving refactor the function not to hold the vfs lock pointlessly while parsing the input. Wrap the access from the read side in READ_ONCE() to appease concurrency checkers. Do not check if return value from snprintf() is negative... Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
