Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
504398f0a7
Stop overloading the __I40EVF_IN_CRITICAL_TASK bit lock to protect the mac_filter_list and vlan_filter_list. Instead, implement a spinlock to protect these two lists, similar to how we protect the hash in the i40e PF code. Ensure that every place where we access the list uses the spinlock to ensure consistency, and stop holding the critical section around blocks of code which only need access to the macvlan filter lists. This refactor helps simplify the locking behavior, and is necessary as a future refactor to the __I40EVF_IN_CRITICAL_TASK would cause a deadlock otherwise.

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.
