In function gfs2_glock_dq, it checks to see if this is the fast path. Before this patch, it checked both "find_first_holder(gl) == NULL" and list_empty(&gl->gl_holders), which is redundant. If gl_holders is empty then find_first_holder must return NULL. This patch removes the redundancy. 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.
