The linux-next integration testing tree
01c51a32dc
Let's test that we can have shared zeropages in our process as long as storage keys are not getting used, that shared zeropages are properly unshared (replaced by anonymous pages) once storage keys are enabled, and that no new shared zeropages are populated after storage keys were enabled. We require the new pagemap interface to detect the shared zeropage. On an old kernel (zeropages always disabled): # ./s390x/shared_zeropage_test TAP version 13 1..3 not ok 1 Shared zeropages should be enabled ok 2 Shared zeropage should be gone ok 3 Shared zeropages should be disabled # Totals: pass:2 fail:1 xfail:0 xpass:0 skip:0 error:0 On a fixed kernel: # ./s390x/shared_zeropage_test TAP version 13 1..3 ok 1 Shared zeropages should be enabled ok 2 Shared zeropage should be gone ok 3 Shared zeropages should be disabled # Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0 Testing of UFFDIO_ZEROPAGE can be added later.

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.
