Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

We don't need to update the original dm request partially when ending
each cloned bio: just update original dm request once when the whole
cloned request is finished. This still allows full support for partial
completion because a new 'completed' counter accounts for incremental
progress as the clone bios complete.
Partial request update can be a bit expensive, so we should try to avoid
it, especially because it is run in softirq context.
Avoiding all the partial request updates fixes both hard lockup and
soft lockups that were easily reproduced while running Laurence's
test[1] on IB/SRP.

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.
