mm, lockdep: annotate reclaim context to zone reclaim too
Commit cf40bd16fd ("lockdep: annotate reclaim context") introduced reclaim
context annotation. But it didn't annotate zone reclaim. This patch do
it.
The point is, commit cf40bd16fd annotate __alloc_pages_direct_reclaim but
zone-reclaim doesn't use __alloc_pages_direct_reclaim.
current call graph is
__alloc_pages_nodemask
get_page_from_freelist
zone_reclaim()
__alloc_pages_slowpath
__alloc_pages_direct_reclaim
try_to_free_pages
Actually, if zone_reclaim_mode=1, VM never call
__alloc_pages_direct_reclaim in usual VM pressure.
