5.4.102 backported a lot of stuff that our WireGuard backport already did, in addition to other patches we had, so those patches were removed from that part of the series. In the process other patches were refreshed or reworked to account for upstream changes. This commit involved `update_kernel.sh -v -u 5.4`.

Subject: [PATCH] wireguard: peer: put frequently used members above cache
|
|
lines
|
|
|
|
commit 5a0598695634a6bb4126818902dd9140cd9df8b6 upstream.
|
|
|
|
The is_dead boolean is checked for every single packet, while the
|
|
internal_id member is used basically only for pr_debug messages. So it
|
|
makes sense to hoist up is_dead into some space formerly unused by a
|
|
struct hole, while demoting internal_api to below the lowest struct
|
|
cache line.
