[Devel] [PATCH RH8 1/3] kstat: fix percpu early linking

[Pavel Tikhomirov]

* init kstat early as possible, before page_alloc_init() and kmem_cache_init()
https://jira.sw.ru/browse/PSBM-36448

Signed-off-by: Konstantin Khlebnikov <khlebnikov at openvz.org>

Without this patch kstat_init() is useless and never called.

https://jira.sw.ru/browse/PSBM-127780
Splited-from: 02bc7ba77b34b ("core: Add glob_kstat, percpu kstat and
account mm stat")
Fixes: 32a31d2ad5e7f ("vzstat: Add base kstat structures and variables")
