ext4: skip project quota tests if the kernel does not support them
In _scratch_enable_pquota, use _notrun if the file system with project
quotas enable can't be mounted, since that indicates the kernel
doesn't support that feature.
This commit removes the redundant chown operation which was supposed to
cause the test file to be copied up. Also, _overlay_scratch_unmount() is
used to unmount the overlay filesystem rather than invoking $UMOUNT_PROG.
This can be used to trigger an assert in the current XFS code
because it can't handle the case where there are COW extents on a
file, but none at or below the range converted by the AIO completion
handler.
Note that it doesn't trigger the assert 100% but fairly reliably.

xfs: test increased overlong directory extent discard threshold
As of 2007, metadump has an interesting "feature" where it discards
directory extents that are longer than 1000 (originally 20) blocks.
This ostensibly was to protect metadump from corrupt bmbt records, but
it also has the effect of omitting from the metadump valid long extents.

btrfs: test incremental send with compression and extent cloning
Test that an incremental send/receive operation will not fail when the
destination filesystem has compression enabled and the source filesystem
has a 4K extent at a file offset 0 that is not compressed and that is
shared.
This currently fails on btrfs and is fixed by the following patch for the
linux kernel:
"Btrfs: incremental send, fix emission of invalid clone operations"

xfs/424: add check for finobt && update comments
1) This test can check if setting types causes error regardless of
supporting crc, so we can update existed comments about it. We
also add new comments about known issues triggered in this test.
2) When finobt is disabled, xfs_db fails to get current address of
free_root, as below:
xfs_db -c "agi" -c "addr free_root" -c "daddr" /dev/sda11
Metadata CRC error detected at xfs_inobt block 0x0/0x1000

Running related tests without finobt makes no sense, so we add
check for finobt.

generic: test read around EOF
As posix standard, if the file offset is at or past the end of file,
no bytes are read, and read() returns zero. There was a bug, when
DIO read offset is just past the EOF a little, but in the same block
with EOF, read returns different negative values.
Kernel commit 74cedf9b6c60 ("direct-io: Fix negative return from dio
read beyond eof") and commit 2d4594acbf6d ("fix the regression from
"direct-io: Fix negative return from dio read beyond eof"") fixed
the bug.
This case reads from range within EOF, past EOF and at EOF, to make
sure the return value as expected, especially read from past/at EOF
returns 0.
[eguan: update commit log and comments about information of the
specific bug, adjust read_test param order (offset, count, ret) and
test description]

common/inject: refactor helpers to use new errortag interface
Refactor the XFS error injection helpers to use the new errortag
interface to configure error injection. If that isn't present, fall
back either to the xfs_io/ioctl based injection or the older sysfs
knobs. Refactor existing testcases to use the new helpers.

common/config: add acl and user_xattr support for TEST_DEV
On RHEL6.9GA, generic/097 fails for ext4 because _test_cycle_mount()
remount ext4 without the user_xattr option, so extended attributes

On some old kernels, ext4 filesystem can not be mounted with acl and

these options by default:
'ea6633369458("ext4: enable acls and user_xattr by default")'
We add acl and user_xattr support in _test_mount_opts(), and it
works normally on all kernels.

common/config: unset TEST_FS_MOUNT_OPTS across config sections
TEST_FS_MOUNT_OPTS doesn't get reset before parsing next config
section, this will cause unexpected TEST_FS_MOUNT_OPTS in test,
because it can be assigned some fs-specific mount options in
_test_mount_opts, which might not be supported by the filesystem in
next config section. And MOUNT_OPTIONS is reset, I don't see why
TEST_FS_MOUNT_OPTS shouldn't be.
Also update README.config-sections to reflect this change and fix
typos (replace MOUNT_OPTIONS with TEST_FS_MOUNT_OPTS).

The $dread_pid refers to the while-true-do loop, wait for $dread_pid

this point we're sure that there's no unfinished background process
