This test seems to check that log sizes scale up properly with the size
of the filesystem, given a carefully controlled set of mkfs parameters.
Since turning on reflink or rmap will change the minimum log size,
change the test to detect their presence and ensure they're disabled.

Create a new helper function to discover the minimum log size that will
work with the mkfs options provided, then remove all the hardcoded block
sizes from various xfs tests. This will be necessary when we turn on
reflink or rmap by default and the minimum log size increases.

This test will test if we can still do the following operations when a
full is full:
- buffered write into unpopulated preallocated extent
- clone the untouched preallocated extent
- fsync
- no data loss if power loss happens after above fsync
Above operations should not fail, as they takes no extra data space.
Xfs passes the test, while btrfs fails at fsync and has data loss.
The fix for btrfs is:
"btrfs: Flush before reflinking any extent to prevent NOCOW write falling
back to CoW without data reservation"

It should return error while changing IMMUTABLE_FL and APPEND_FL if the
process has no capability CAP_LINUX_IMMUTABLE.
However, it's not true on overlayfs after kernel version v4.19 since

The recent commit 4529b20e1a ("btrfs/048: amend property validation
cases"), does not properly filter the scratch device because the error
messages are sent to stderr and not to stdout, and the pipe filter only
gets input from the stdout of the btrfs utility. We need to redirect the
stderr of the btrfs utility to its stdout.
Further, the golden output had the path "/mnt/scratch" hardcoded, instead
of using SCRATCH_MNT. Fix that as well.
The test was failing on any setup where the scratch device is not mounted
at "/mnt/scratch".

Stress send running in parallel with balance and deduplication against
files that belong to the snapshots used by send. The goal is to verify
that these operations running in parallel do not lead to send crashing
(trigger assertion failures and BUG_ONs), or send finding an inconsistent
snapshot that leads to a failure (reported in dmesg/syslog). The test
needs big trees (snapshots) with large differences between the parent and
send snapshots in order to hit such issues with a good probability.
This currently fails on btrfs, hitting a BUG_ON() often, and with btrfs
error messages in dmesg/syslog. The problem has always existed and it is
not new, but probably unnoticed due to lack of test cases that exercise
these btrfs features running in parallel.
The following patches for btrfs fix the problems:
"Btrfs: fix race between send and deduplication that lead to failures and
crashes"
"Btrfs: prevent send failures and crashes due to concurrent relocation"

Remove the require_{test,scratch]* sentinel files after a test fails.
This eliminates false fsck corruption reports such as the following:
1. Test A calls _require_scratch, which creates the sentinel file
$RESULT_DIR/require_scratch to facilitate fsck after the test completes.
2. Test A runs some test, which corrupts the scratch filesystem due to
kernel bug or something.
3. Test A calls _fail because of the errors in (2). Note that the test
case returned 1, so ./check unmounts the test and scratch filesystems
without checking them or removing $RESULT_DIR/require_scratch
4. Test B starts up, but does not call _require_scratch. The
$RESULT_DIR/require_scratch file is still there.
5. Test B completes successfully.
6. ./check calls _check_filesystems, which sees the
$RESULT_DIR/require_scratch file and runs fsck.
7. fsck reports the corrupt scratch device (which is associated with
test B) even though B did not ever touch the scratch device and it was
actually test A that corrupted the filesystem.
Note that with the "check: wipe scratch devices between tests" patch
applied, we can also reproduce this problem by running xfs/172 and
xfs/195 with a scratch device small enough that the files created in 172
span multiple AGs and therefore cause 172 to fail.

fssum to find xattrs and make them contribute to the checksum of a

or not supposed to exist xattrs (i.e. that an incremental btrfs send does

Currently fsstress does not exercise creating, reading or deleting xattrs
on files or directories. This change adds support for setting xattrs on
files and directories, using only the xattr user namespace (the other
namespaces are not general purpose and are used for security, capabilities,
ACLs, etc). This adds a counter for each file entry structure that keeps
track of the number of xattrs set for the file entry, and each new xattr
has a name that includes the counter's value (example: "user.x4").
Values for the xattrs have at most 100 bytes, which is more than the
maximum size supported for all major filesystems.

The copy_file_range() test detection code performs a zero-length
copy to determine whether to perform such calls during the test run.
While this detects the common case of syscall availability,
copy_file_range() has a somewhat variable implementation on the
kernel side that can depend on certain per-filesystem features, etc.
In some implementations, a zero length copy can shortcut and return
success before ever invoking per-filesystem functionality and thus
not thoroughly testing the copy mechanism on the current system.
This can cause the test detection code to pass only to run into an
immediate failure on the first copy_file_range() call during the
test.
Tweak test_copy_range() to perform a small single byte copy to avoid
this problem. Also fix a typo bug in the errno check of the clone
range detection logic.
