[PATCH 1/2] mm/memcontrol: do not tweak node in mem_cgroup_init()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



mem_cgroup_init() request for allocations from each possible node, and
it's used to be a problem because NODE_DATA is not allocated for offline
node. Things have already changed since commit 09f49dca570a9 ("mm: handle
uninitialized numa nodes gracefully"), so it's unnecessary to check for
!node_online nodes here.
