Subject: SLUB: Do our own flags based on PG_active and PG_error
X-Git-Tag: v2.6.22-rc2~55

SLUB: Do our own flags based on PG_active and PG_error

The atomicity when handling flags in SLUB is not necessary since both flags
used by SLUB are not updated in a racy way.  Flag updates are either done
during slab creation or destruction or under slab_lock.  Some of these flags
do not have the non atomic variants that we need.  So define our own.
