vmscan: add shrink_slab tracepoints
commit 095760730c1047c69159ce88021a7fa3833502c8 upstream.
Stable note: This patch makes later patches easier to apply but otherwise
has little to justify it. It is a diagnostic patch that was part
of a series addressing excessive slab shrinking after GFP_NOFS
failures. There is detailed information on the series' motivation
at https://lkml.org/lkml/2011/6/2/42 .
It is impossible to understand what the shrinkers are actually doing
without instrumenting the code, so add a some tracepoints to allow
insight to be gained.
