Because the set/clear SBI_IS_RESIZEFS flag not between any locks,
In the following case:
thread1 thread2
->ioctl(resizefs)
->set RESIZEFS flag ->ioctl(resizefs)
... ->set RESIZEFS flag
->clear RESIZEFS flag
->resizefs stream
# No RESIZEFS flag in the stream
Also before freeze_super, the resizefs not started, we should not set
the SBI_IS_RESIZEFS flag.
So move the set/clear SBI_IS_RESIZEFS flag between the cp_mutex and
gc_lock.

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 Restructured Text 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.
