This test does some weird things with live filesystems -- it seems to be
validating the behavior of fstrim by comparing the filesystem's free
space map to holes in the file image that backs the filesystem.
However, this doesn't account for the fact that some filesystems
maintain in-core preallocations and/or can perturb the free space data
during unmount. This causes sporadic test failures when the two become
out of sync.
Therefore, make sure we unmount the filesystem before we start running
tools against the filesystem image file to eliminate the possibility of
changes to the free space map. This was found by running shared/298 on
xfs with a 1k block size.

Helper functions are supposed to have a leading underscore ('_') in the

test cases (generic/349-351) /do/ have the leading underscore, so now
they're broken.

The sanity test case in those tests (i.e. 13..17)
are all skipped in fs with no falloc support, but the tests
are reported to pass.
For example, from 445.full:
File system supports the default behavior.
File system does not support fallocate.
Allocation size: 4096
17. Test file with unwritten extents, data-hole-data inside page
Test skipped as fs doesn't support unwritten extents.
Explicitly check for falloc support before running those tests
so they would be properly reported as skipped.

The dm-log-writes replay mechanism issues discards to provide
zeroing functionality to prevent out-of-order replay issues. These
discards don't always result in zeroing bevavior, however, depending
on the underlying physical device. In turn, this causes test
failures on XFS v5 filesystems that enforce metadata log recovery
ordering if the filesystem ends up with stale data from the future
with respect to the active log at a particular recovery point.
To ensure reliable discard zeroing behavior, use a thinly
provisioned volume as the data device instead of using the scratch
device directly. This slows the test down slightly, but provides
reliable functional behavior at a reduced cost from active snapshot
management or forced zeroing.

The dm-log-writes infrastructure is currently implemented to use
SCRATCH_DEV as a hardcoded data device. In preparation to allow use
of specialized devices in certain circumstances, genericize the code
to allow an arbitrary data device. This requires passing the target
device as a parameter to several helper functions from various
tests. No functional changes.

Jeff Mahoney pointed out that 'security.evm' actually has an expected
value format, which breaks the test if EVM is enabled. It turns out
that the 'security.evm' setxattr call in the original syzkaller report
was a total red herring, as this bug can be reproduced without it.
Fix the test case to do the minimum amount of work needed to reproduce
the corruption.

For some filesystem, such as vfat, the max support file size is 4G.
We limit the max size and let the test go on running.
Fix it by moving the function get_max_file_size() of generci/485 to

Additionally modify the test to create larger - 3gb filesystem in the

A test to perform reads/writes under various cgroups and verify that
I/Os are accounted properly according to cgroup aware writeback.
This is a generic test, but not all commonly used local filesystems
support cgroup aware writeback at the moment (i.e., XFS). Therefore,
this test currently requires ext4 or btrfs for the time being.
The common/cgroup2 file is copied from a separate cgroup related
