[PATCH v1 0/6] TLS read_sock performance scalability

From: Chuck Lever <[email protected]>

I'd like to encourage in-kernel kTLS consumers (i.e., NFS and
NVMe/TCP) to coalesce on the use of read_sock. When I suggested
this to Hannes, he reported a number of nagging performance
scalability issues with read_sock. This series is an attempt to
run these issues down and get them fixed before we convert the
above sock_recvmsg consumers over to read_sock.

Each patch's commit message speaks for itself, so I won't repeat
that content here.

Series is based on commit ab99e1167293 ("Merge branch
'net-ethtool-track-tx-pause-storm'") in the net-next tree.
