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
common/rc, and add the max filesize limit to generic/299.

Add support for btrfs in shared/298. Achieve this by introducing 2
new awk scripts that parse relevant btrfs structures and print holes.
Additionally modify the test to create larger - 3gb filesystem in the
case of btrfs. This is needed so that distinct block groups are used
for data and metadata.

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
patch from Shaohua Li that never made it upstream.

XFS had a use-after-free bug when xfs_xattr_put_listent runs out of
listxattr buffer space while trying to store the name
"system.posix_acl_access" and then corrupts memory by not checking
the seen_enough state and then trying to shove
"trusted.SGI_ACL_FILE" into the buffer as well.
In order to tickle the bug in a user visible way we must have
already put a name in the buffer, so we take advantage of the fact
that "security.evm" sorts before "system.posix_acl_access" to make
sure this happens.

Currently generic/075 and generic/112 have two extra fsx passes each
that exercise fsx with preallocation, which are only enabled for
XFS.
These tests can also be run with other file systems, given that the
XFS prealloc ioctls are implemented in generic code since the
addition of the fallocate system call. This also means a version of
XFS that does not support preallocation (e.g. because it always
writes out of place) can skip the prealloc tests while still
completing the normal fsx tests just fine.

Test that after a combination of file renames, linking and creating

file, after a power failure we are able to mount the filesystem and
all file names correspond to the correct inodes.
This test is motivated by a bug found in btrfs, which is fixed by
applying the following two patches to the linux kernel:
"[PATCH 1/2] Btrfs: fix fsync after succession of renames of different files"
"[PATCH 2/2] Btrfs: fix fsync after succession of renames and unlink/rmdir"
The test passes on ext4, xfs and patched btrfs, however at least in
a 5.0-rc5 linux kernel, it fails on f2fs.

This test has the number of files/dirs created by xfsrestore hardcoded
in golden output.
When fsstress is added new ops, the number of files/dirs created with
the same random seed changes and this regularly breaks this test,
so when new fsstress ops are added they should be either added to the
dump test blacklist or golden output of this test needs to be ammended
to reflect the change.
The golden output includes only the file count reported by xfsrestore
and test does not even verify that this is the correct file count.
Instead, leave the golden output neutral and explicitly verify that
file count before and after the test are the same.
With this change, the test becomes agnostic to fsstress ops and we
could also stop blacklisting clone/dedup/copy ops if we want.

overlay/061 is currently the only overlay test that is expected to
fail on upstream kernel.
It is a flavor of test overlay/016 with mread in stead of pread.
The ro/rw inconsistencies related to file read()/write() API were
fixed with stacked file operations in v4.19, but the ro/rw
inconsistencies related to shared mmap read/write remain to be
fixed.
The test currently checks cache coherency between mmap read and file
write(), but this sort of cache coherency is a Linux implementation
detail not a requirement of the API.
Instead of mread vs. pwrite, check consistency of mread vs. mwrite
to shared mmap, which is required by the MMAP_SHARED API.
Because we can, perform the test on shared memory that maps files
that are already close and check also that mwrite after file is
closed is persistent. This adds test coverage for future overlayfs
writeback code.
