The first patch > includes memory barriers to synchronize queue descriptor > reads. The second patch fixes a memory leak that could > occur if the device returns a TX completion with an error > code in the descriptor, in which case the respective socket > buffer and other relevant data structures may not be freed > or updated properly. > > v3: Correct length of Fixes tags, requested by Jakub Kicinski > > v2: Provide more detailed comments explaining specifically what > reads are being ordered, suggested by Michael Ellerman Series applied, thanks!
