Recent changes (especially05cd271fd6("cls_flower: Support multiple masks per priority")) in the fl_flow_mask structure grow it and its current size e.g. on x86_64 with defconfig is 760 bytes and more than 1024 bytes with some debug options enabled. Prior the mentioned commit its size was 176 bytes (using defconfig on x86_64). With regard to this fact it's reasonable to allocate this structure dynamically in fl_change() to reduce its stack size. v2: - use kzalloc() instead of kcalloc() Fixes:05cd271fd6("cls_flower: Support multiple masks per priority") Cc: Jiri Pirko <jiri@resnulli.us> Cc: Paul Blakey <paulb@mellanox.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.

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.
