Change do_withdraw() to clear the SDF_JOURNAL_LIVE flag under the log flush lock. In addition, change __gfs2_trans_begin() to check if the filesystem is already known to be withdrawn using gfs2_withdrawn(). Then, once we are holding the log flush lock, check if the SDF_JOURNAL_LIVE flag is still set. This second check ensures that the filesystem will remain live until the transaction is submitted. With these changes, it is no longer useful to clear SDF_JOURNAL_LIVE in gfs2_end_log_write() after calling gfs2_withdraw(). Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
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.
