The following commit has been merged in the master branch: commit 44a8c4f33c0073ca614db79f22e023811bdd0f3c Merge: 3ab1270bfa1e8ae7db0d46fee90c5db2935ac91b c70672d8d316ebd46ea447effadfe57ab7a30a50 Author: Jakub Kicinski <kuba(a)kernel.org> Date: Fri Sep 4 21:18:58 2020 -0700 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net We got slightly different patches removing a double word in a comment in net/ipv4/raw.c - picked the version from net. Simple conflict in drivers/net/ethernet/ibm/ibmvnic.c. Use cached values instead of VNIC login response buffer (following what commit 507ebe6444a4 ("ibmvnic: Fix use-after-free of VNIC login response buffer") did).
