This change is prep work for moving some work from __journal_entry_close() to journal_entry_open(): without this change, journal_entry_open() doesn't know if it's going to be able to open a new journal entry until the cmpxchg loop, meaning it can't create the new journal pin entry and update other global state because those have to be done prior to the cmpxchg opening the new journal entry. Fortunately, we don't call bch2_journal_halt() from interrupt context. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.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.
