Subject: [PATCH net 0/2] ibmvnic: Bug fixes for queue descriptor processing
Date: Tue, 24 Nov 2020 11:26:14 -0600 [thread overview]
Message-ID: <1606238776-30259-1-git-send-email-tlfalcon@linux.ibm.com> (raw)
This series resolves a few issues in the ibmvnic driver's
RX buffer and TX completion processing. 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.
