Now that we've established (again!) that empty xattr leaf buffers are ok, we no longer need to bhold them to transactions when we're creating new leaf blocks. Get rid of the entire mechanism, which should simplify the xattr code quite a bit. The original justification for using bhold here was to prevent the AIL from trying to write the empty leaf block into the fs during the brief time that we release the buffer lock. The reason for /that/ was to prevent recovery from tripping over the empty ondisk block. Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Darrick J. Wong <djwong@kernel.org>
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.
