In the memory offline test, the $ration was used with RANDOM as the
possibility to get it offlined, correct it to become the portion of
available removable memory blocks.
Also ask the tool to try to offline the next available memory block
if the attempt is unsuccessful. It will only fail if all removable
memory blocks are busy.
A nice example:
$ sudo ./test.sh
Test scope: 10% hotplug memory
online all hot-pluggable memory in offline state:
SKIPPED - no hot-pluggable memory in offline state
offline 10% hot-pluggable memory in online state
trying to offline 3 out of 28 memory block(s):
online->offline memory1
online->offline memory10
./test.sh: line 74: echo: write error: Resource temporarily unavailable
offline_memory_expect_success 10: unexpected fail
online->offline memory100
online->offline memory101
online all hot-pluggable memory in offline state:
offline->online memory1
offline->online memory100
offline->online memory101
skip extra tests: debugfs is not mounted
$ echo $?

Use md5sum so that it takes less time of checking
trace logs update. Since busybox tail/cat takes too
long time to read the trace log, this uses md5sum
to check whether trace log is updated or not.

Sysctl test will fail in some items if the value of /proc/sys/kernel
/sysctrl_writes_strict is 0 as the default value in kernel older than v4.5.
Make this test more robus and compatible with older kernel by checking and

Build of aperf fails as below:

/tmp/ccKf3GF6.o: In function `main':
aperf.c:(.text+0x278): undefined reference to `sqrt'
collect2: error: ld returned 1 exit status
```
The faulure occurs because -lm was defined as LDFLAGS and implicit rule
of make places LDFLAGS before source file. This commit fixes the
problem by using LDLIBS instead of LDFLAGS.

The build fails because output file is specified without $(OUTPUT) and
LDFLAGS is used though Makefile implicit rule is used. This commit
fixes the error by specifying output file path with $(OUTPUT) and using

Since older kernel didn't support separated instance of
set_ftrace_filter, if the test case set the filter in
an instance, it will propagate to top-level instance.
This means that the filter setting remains even if we
remove the instance, and will cause other tests failure.
To avoid this issue, reset the ftrace filter if we
detect the propagation.

The seccomp/test_harness.h file contains useful helpers to build tests.
Moving it to the selftest directory should benefit to other test
components.
Keep seccomp maintainers for this file.

The "Sync framework" test doesn't work if the kernel has no support,
obviously. Rather than reporting a failure, check for the kernel support
by looking for /sys/kernel/debug/sync/sw_sync, and if not found skip the
test.

Most of the tests under selftests follow a pattern for their results,
which can then be parsed easily by other external tools easily. Though
futex tests do print the test results very well, it doesn't really
follow the general selftests pattern.
This patch makes necessary changes to fix that.
Output before this patch:
futex_requeue_pi: Test requeue functionality
Arguments: broadcast=0 locked=0 owner=0 timeout=0ns
Result: PASS
Output after this patch:
futex_requeue_pi: Test requeue functionality
Arguments: broadcast=0 locked=0 owner=0 timeout=0ns

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"libnvdimm updates for the latest ACPI and UEFI specifications. This
pull request also includes new 'struct dax_operations' enabling to
undo the abuse of copy_user_nocache() for copy operations to pmem.
The dax work originally missed 4.12 to address concerns raised by Al.
Summary:
- Introduce the _flushcache() family of memory copy helpers and use
them for persistent memory write operations on x86. The
_flushcache() semantic indicates that the cache is either bypassed
for the copy operation (movnt) or any lines dirtied by the copy
operation are written back (clwb, clflushopt, or clflush).
- Extend dax_operations with ->copy_from_iter() and ->flush()
operations. These operations and other infrastructure updates allow
all persistent memory specific dax functionality to be pushed into
libnvdimm and the pmem driver directly. It also allows dax-specific
sysfs attributes to be linked to a host device, for example:
/sys/block/pmem0/dax/write_cache
- Add support for the new NVDIMM platform/firmware mechanisms
introduced in ACPI 6.2 and UEFI 2.7. This support includes the v1.2
namespace label format, extensions to the address-range-scrub
command set, new error injection commands, and a new BTT
(block-translation-table) layout. These updates support inter-OS
and pre-OS compatibility.
- Fix a longstanding memory corruption bug in nfit_test.
- Make the pmem and nvdimm-region 'badblocks' sysfs files poll(2)
capable.
- Miscellaneous fixes and small updates across libnvdimm and the nfit
driver.

The root cause of panic is the num_pm of nfit_test1 is wrong.
Though 1 is specified for num_pm at nfit_test_init(), it must be 2,
because nfit_test1->spa_set[] array has 2 elements.
Since the array is smaller than expected, the driver breaks other area.
(it is often the link list of devres).
As a result, panic occurs like the following example.

Toggle display total number of events by guest (debugfs only).
When switching to display of events by guest, field filters remain
active. I.e. the number of events per guest reported considers only
events matching the filters. Likewise with pid/guest filtering.
Note that when switching to display of events by guest, DebugfsProvider
remains to collect data for events as it did before, but the read()
method summarizes the values by pid.

Display a (possibly inaccurate) list of all running guests. Note that we
leave a bit of extra room above the list for potential error messages.
Furthermore, we deliberately do not reject pids or guest names that are
not in our list, as we cannot rule out that our fuzzy approach might be
in error somehow.

'Current' can be misleading as it doesn't tell whether this is the amount
of events in the last interval or the current average per second.
