Before this patch, function freeze_go_sync, called when promoting the freeze glock, was testing for the SDF_JOURNAL_LIVE superblock flag. That's only set for read-write mounts. Read-only mounts don't use a journal, so the bit is never set, so the freeze never happened. This patch removes the check for SDF_JOURNAL_LIVE for freeze requests but still checks it when deciding whether to flush a journal. Signed-off-by: Bob Peterson <rpeterso@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 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.
