The wake_up_var interface is fragile as barriers are sometimes needed. There are now new interfaces so that most wake-ups can use an interface that is guaranteed to have all barriers needed. This patch changes the wake up on cl_cb_inflight to use atomic_dec_and_wake_up(). It also changes the wake up on rp_locked to use store_release_wake_up(). This involves changing rp_locked from atomic_t to int. Signed-off-by: NeilBrown <neilb@suse.de> Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Chuck Lever <chuck.lever@oracle.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.
