This patch enables debugfs file /sys/kernel/debug/ion/heaps/system_shrink
to shrink pool and get pool size. This technically enables debugfs
shrinking for all heaps, not just the system heap although the system heap
is the only one with a shrinker right now. It is already implemented
but not comple
Hello,
The ion has internal page pool to keep freed pages.
There is no way to shrink the pool so that the pool sometimes
grows too big.
For example my platform allocates some graphic memory via ion.
Sometimes the pool can be several hundreds MB. I want to
flush the pool before critical page short
This patch shrink page-pool by page unit.
The system shrinker calls ion_heap_shrink_count() to get nr_to_scan,
and pass it to ion_heap_shrink_scan().
The problem is the return value of ion_heap_shrink_count() is the number
of pages but ion_system_heap_shrink(), which is called by
ion_heap_shrink_s

This patch fixes the checkpatch.pl warning:
WARNING: Macros with flow control statements should be avoided
Replace the macro with a function doing the exact same task as the
