[PATCH 0/2] vtime: Remove pair of seqcount on context switch

[Frederic Weisbecker]

Extracted from a larger queue that fixes kcpustat on nohz_full, these
two patches have value on their own as they remove two write barriers
on nohz_full context switch.

Frederic Weisbecker (2):
  vtime: Rename vtime_account_system() to vtime_account_kernel()
  vtime: Spare a seqcount lock/unlock cycle on context switch
