Linux kernel source tree
d0c8f338ab
When Ethernet frames span mulitple URBs, the netdev buffer memory pointed to by the asix_rx_fixup_info structure remains allocated during the time gap between the 2 executions of asix_rx_fixup_internal(). This means that if ax88772_unbind() is called within this time gap to free the memory of the parent private data structure then a memory leak of the part filled netdev buffer memory will occur. Therefore, create a new function asix_rx_fixup_common_free() to free the memory of the netdev buffer and add a call to asix_rx_fixup_common_free() from inside ax88772_unbind(). Consequently when an unbind occurs part way through receiving an Ethernet frame, the netdev buffer memory that is holding part of the received Ethernet frame will now be freed.

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.
