Function gfs2_trans_add_meta() checks for the SDF_FROZEN flag to make sure that no buffers are added to a transaction while the filesystem is frozen. With the recent freeze/thaw rework, the SDF_FROZEN flag is cleared after thaw_super() is called, which is sufficient for serializing freeze/thaw. However, other filesystem operations started after thaw_super() may now be calling gfs2_trans_add_meta() before the SDF_FROZEN flag is cleared, which will trigger the SDF_FROZEN check in gfs2_trans_add_meta(). Fix that by checking the s_writers.frozen state instead. In addition, make sure not to call gfs2_assert_withdraw() with the sd_log_lock spin lock held. Check for a withdrawn filesystem before checking for a frozen filesystem, and don't pin/add buffers to the current transaction in case of a failure in either case.

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.
