XFS v5 superblock fs' use metadata LSN tracking to determine when an
on-disk structure was last written to disk. This is used to ensure log
recovery operates correctly after an unclean shutdown. To work
correctly, the on-disk metadata LSNs must always remain behind the
current LSN with respect to the log.
Historically, xfs_repair had a problem where it incorrectly formats the
log to an LSN that is potentially behind existing metadata LSNs. As
such, xfs_repair and the kernel have been updated to prevent, detect and
recover from the problem. Add a test that intentionally formats the log
incorrectly and verifies that the fs fails to mount and that xfs_repair
detects the invalid metadata LSNs.

The xfsprogs libxfs layer implements its own log formatting code to
support utilities that might need to format the log, such as mkfs,
repair, metadump, etc. This code is fairly independent from kernel log
writing code. Therefore, add a test that reformats the log from
userspace with various supported log stripe unit alignments and verifies
that the end result is a correctly formatted log.

Currently _link_output_file() selects output file suffix based on the
current operating system. Make it more versatile by allowing selection
of output file suffix based on any feature string. The idea is that
in config file ($seq.cfg) there are several lines like:
feat1,feat2: suffix
The function is passed a feature string (or uses os_name,MOUNT_OPTIONS
if no argument is passed) and selects output file with a suffix for
which all features are present in the feature string. If there is no
matching line, output with 'default' suffix is selected.
Update all tests using _link_out_file to the new calling convention.

Teach _check_dmesg to look for improper RCU usage and circular locking

to a real problem in the filesystem's implementation (or the current

Test that doing a direct IO write against a file range that contains one
prealloc extent and one compressed extent works correctly.
From the linux kernel 4.0 onwards, this either triggered an assertion
failure (leading to a BUG_ON) when CONFIG_BTRFS_ASSERT=y or resulted
in an arithmetic underflow of an inode's space reservation for write
operations.

This issue was found by testing f2fs module with generic/285, and the
related bug has already been fixed since commit 2e023174a88d ("f2fs:
avoid data offset overflow when lseeking huge file"), but forgot to fix
it in xfstest suit.
The wrong result printed is printed in log below:
10. Test a huge file for offset overflow
10.01 SEEK_HOLE expected 65536 or 0, got 65536. succ
10.02 SEEK_HOLE expected 65536 or 0, got 65536. succ
10.03 SEEK_DATA expected 0 or 0, got 0. succ
10.04 SEEK_DATA expected 1 or 1, got 1. succ
10.05 SEEK_HOLE expected 0 or 0, got 0. FAIL
10.06 SEEK_DATA expected -65536 or -65536, got -65536. succ
10.07 SEEK_DATA expected -65535 or -65535, got -65535. succ
10.08 SEEK_DATA expected -65536 or -65536, got -65536. FAIL
The result printed in the log shows that when some test cases failed, the
data we expected and got are the same that is not correct obviously.
The reason is that we cast the result from type off_t(64-bit) to type
long(32-bit) when doing huge file offset seeking tests in 32-bit machine.
This patch fixes the wrong printing issue.
