commit b3143b9a38d5039bcd1f2d1c94039651bfba8043 upstream. responding to ->suspend_lo and ->suspend_hi is similar to responding to ->suspended. It is best to wait in the common core code without incrementing ->active_io. This allows mddev_suspend()/mddev_resume() to work while requests are waiting for suspend_lo/hi to change. This is will be important after a subsequent patch which uses mddev_suspend() to synchronize updating for suspend_lo/hi. So move the code for testing suspend_lo/hi out of raid1.c and raid5.c, and place it in md.c Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Shaohua Li <shli@fb.com> Signed-off-by: Jack Wang <jinpu.wang@profitbricks.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
