Currently, if the gc is running, when the allocator found free_inc is empty, allocator has to wait the gc finish. Before that, the IO is blocked. But actually, there would be some buckets is reclaimable before gc, and gc will never mark this kind of bucket to be unreclaimable. So we can put these buckets into free_inc in gc running to avoid IO being blocked.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
