UPSTREAM: virtiofs: add logic to free up a memory range ...
Add logic to free up a busy memory range. Freed memory range will be
returned to free pool. Add a worker which can be started to select
and free some busy memory ranges.
Process can also steal one of its busy dax ranges if free range is not
available. I will refer it to as direct reclaim.
If free range is not available and nothing can't be stolen from same
inode, caller waits on a waitq for free range to become available.
For reclaiming a range, as of now we need to hold following locks in
specified order.
down_write(&fi->i_mmap_sem);
down_write(&fi->dax->sem);
We look for a free range in following order.
A. Try to get a free range.
B. If not, try direct reclaim.
C. If not, wait for a memory range to become free
