[Devel] [PATCH 0/4] Make kstat_glob::swap_in percpu and cleanup

[Kirill Tkhai]

This patchset continues escaping of kstat_glb_lock
and makes swap_in percpu. Also, newly unused primitives
are dropped and reduced memory usage by using percpu
seqcount (instead of separate percpu seqcount for every
kstat percpu variable).

Kirill Tkhai (4):
      kstat: Make kstat_glob::swap_in percpu
      kstat: Drop global kstat_lat_struct
      kstat: Drop cpu argument in KSTAT_LAT_PCPU_ADD()
      kstat: Make global percpu kstat_pcpu_seq instead of percpu seq for every variable
