[PATCH 28/28] vdso: Rename struct arch_vdso_data to arch_vdso_time_data
From: Thomas Weißschuh
Date: Thu Oct 10 2024 - 04:14:59 EST
From: Nam Cao <namcao@xxxxxxxxxxxxx>
The struct arch_vdso_data is only about vdso time data. So rename it to
arch_vdso_time_data to make it obvious.
Non time-related data will be migrated out of these structs soon.
Signed-off-by: Nam Cao <namcao@xxxxxxxxxxxxx>
