In case of external metadata arrays spare disks are added to containers
first. mdadm keeps monitoring /proc/mdstat output and when spare disk is
available, it moves it from the container to the array. The problem is
there is no notification of new spare disk in the container and mdadm
waits a long time (until timeout) before it takes the action.

Change common RUN_TESTS to print messages in user friendly TAP13 format.
This change add TAP13 header at the start of RUN_TESTS target run, and
prints the resulting pass/fail messages with test number information in
the TAP 13 format for each test in the run tests list.
This change covers test scripts as well as test programs. Test programs
have an option to use ksft_ API, however test scripts won't be able to.
With this change, test scripts can print TAP13 format output without any
changes to individual scripts.
Test programs can provide TAP13 format output as needed as some tests
already do. Tests that haven't been converted will benefit from this
change. Tests that are converted benefit from the test counts for all
the tests in each test directory.
Running firmware tests:
make --silent -C tools/testing/selftests/firmware/ run_tests

Before this patch, if GFS2 encountered IO errors while writing to
the journal, it would not report the problem, so they would go
unnoticed, sometimes for many hours. Sometimes this would only be
noticed later, when recovery tried to do journal replay and failed
due to invalid metadata at the blocks that resulted in IO errors.
This patch makes GFS2's log daemon check for IO errors. If it
encounters one, it withdraws from the file system and reports
why in dmesg. A similar action is taken when IO errors occur when
writing to the system statfs file.
These errors are also reported back to any callers of fsync, since
that requires the journal to be flushed. Therefore, any IO errors
that would previously go unnoticed are now noticed and the file
system is withdrawn as early as possible, thus preventing further
file system damage.
Also note that this reintroduces superblock variable sd_log_error,
which Christoph removed with commit f729b66fca.

manifest would be stored and later selected runtime based on the hw
pcm params. For legacy, module data is filled in the 0th index of

To accommodate both models, change the relevant structures and populate

And since we unconditionally (re)build the sysctl for all possible

When disabling cpuset.sched_load_balance we expect to be able to online
CPUs without generating sched_domains. However this is currently
completely broken.
What happens is that we generate the sched_domains and then destroy
them. This is because of the spurious 'default' domain build in
cpuset_update_active_cpus(). That builds a single machine wide domain
and then schedules a work to build the 'real' domains. The work then
finds there are _no_ domains and destroys the lot again.
Furthermore, if there actually were cpusets, building the machine wide
domain is actively wrong, because it would allow tasks to 'escape' their
cpuset. Also I don't think its needed, the scheduler really should
respect the active mask.
