The debugfs_remove_recursive() will wait for debugfs_file_put() to return,
so the shrinker will not be freed when doing debugfs operations (such as
shrinker_debugfs_count_show() and shrinker_debugfs_scan_write()), so there
is no need to hold shrinker_rwsem during debugfs operations.

Currently, the shrinker instances can be divided into the following three

Currently, the synchronize_shrinkers() is only used by TTM pool. It only
requires that no shrinkers run in parallel.
After we use RCU+refcount method to implement the lockless slab shrink,
we can not use shrinker_rwsem or synchronize_rcu() to guarantee that all
shrinker invocations have seen an up
Currently, we maintain two linear arrays per node per memcg, which are
shrinker_info::map and shrinker_info::nr_deferred. And we need to resize
them when the shrinker_nr_max is exceeded, that is, allocate a new array,
and then copy the old array to the new array, and finally free the old
array by R
The shrinker_rwsem is a global read-write lock in shrinkers subsystem,
which protects most operations such as slab shrink, registration and
unregistration of shrinkers, etc. This can easily cause problems in the
following cases.
1) When the memory pressure is high and there are many filesystems
Like global slab shrink, this commit also uses refcount+RCU method to make
memcg slab shrink lockless.
Use the following script to do slab shrink stress test:
```
DIR="/root/shrinker/memcg/mnt"
do_create()
{
mkdir -p /sys/fs/cgroup/memory/test
echo 4G > /sys/fs/cgroup/memory/test/memory
For now, reparent_shrinker_deferred() is the only holder of read lock of
shrinker_rwsem. And it already holds the global cgroup_mutex, so it will
not be called in parallel.
Therefore, in order to convert shrinker_rwsem to shrinker_mutex later,
here we change to hold the write lock of shrinker_rwse
Now there are no readers of shrinker_rwsem, so we can simply replace it
with mutex lock.

The dma-buf backend is supposed to provide its own vm_ops, but some
implementation just have nothing special to do and leave vm_ops
untouched, probably expecting this field to be zero initialized (this
is the case with the system_heap implementation for instance).
Let's reset vma->vm_ops to NULL to

For_each_set_bit wants the max number of bits to walk and not the byte
storage size of the source field.
In this case there is no bug since abox_mask can mostly contain bits 0-2.
Another funny thing is that both sizeof(abox_mask), where abox_mask is
unsigned long, and BITS_
