Maxime Chevallier says: ==================== net: mvpp2: Remove unnecessary dynamic allocs Some utility functions in mvpp2 make use of dynamic alloc to exchange temporary objects representing Parser Entries (which are generic filtering entries in the PPv2 controller). These objects are small (44 bytes each), we can use the stack to exchange them. Some previous discussion on this topic showed that the mvpp2_prs_hw_read, which initializes a struct mvpp2_prs_entry based on one of its fields, can easily lead to erroneous code if we don't zero-out the struct beforehand : https://lkml.org/lkml/2018/3/21/739 To fix this, I propose to rename mvpp2_prs_hw_read into mvpp2_prs_init_from_hw, make it zero-out the struct and take the index as a parameter. That's what's done in the first patch of the series. The second patch is the V3 of ("net: mvpp2: Don't use dynamic allocs for local variables"), making use of mvpp2_prs_init_from_hw and taking previous comments into account. ==================== Signed-off-by: David S.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
