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.
