vdso: Preparations for generic data storage

[PATCH 28/28] vdso: Rename struct arch_vdso_data to arch_vdso_time_data

Posted by Thomas Weißschuh 1 month, 2 weeks ago

From: Nam Cao <namcao@linutronix.de>

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.

vdso: Rename struct arch_vdso_data to arch_vdso_time_data

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.

vdso: Rename struct arch_vdso_data to arch_vdso_time_data

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.
