This commit adds fzero operation support for fsstress, which is meant to
exercise fallocate FALLOC_FL_ZERO_RANGE support.
Also reorganise the common fallocate code into a single do_fallocate()
function and use flags use the right mode.
Also in order to make more obvious which fallocate mode fsstress is
testing translate fallocate flags into human readable strings.

and define it manually in every tool using fallocate.

This change allows xfstests runs to simulate apps
which don't bother to call XFS_IOC_DIOINFO, and simply
issue DIO in sizes and alignments of its own choosing.
So i.e.:
# export XFS_DIO_MIN=512
prior to an xfstests run, and these test binaries
should issue 512-aligned DIOs instead of whatever
XFS_IOC_DIOINFO says (i.e. instead of maybe 4k).
(This is in preparation for allowing 512 IOs on
"advanced format" 512/4k disks, when xfs has an
internal 4k sector size).

In some environment, Running 080 fails with many errors.
It happens because ltp/rwtest.sh assumes /bin/sh is `bash' and it's not
always true (ex. /bin/sh is `dash' in Debian.) This script should

This patch replaces the INSTALL macro with LTINSTALL so that libtool is used
to install the applications. Libtool will install the binary from the proper
location and display a warning if any shared library dependancies are not
properly installed. This ensures that a libtool wrapper shell script is not
installed in place of application when libtool wrappers are being used.

This explicitly sends MS_SYNC as the flag to msync() in
fsx.c, in domapwrite(). Without this flag, the memory
written to the mmap'ed region will not be flushed to disk;
in fact, on Linux, calling msync() with a '0' or MS_ASYNC
flag is a no-op.

I was running 068 to test freeze changes, and realized that

although fsync & fdatasync are. It seems to me that sync should

Add two new operations:
- getattr: ioctl(fd, FS_IOC_GETFLAGS, &fl)
- setattr: ioctl(fd, FS_IOC_SETFLAGS, &random_flags)
Attribute mask may be passed via -M opt, by default is (~0).
By default FS_IOC_SETFLAGS has zero probability because
it may produce inodes with APPEND or IMMUTABLE flags which
are not deletable by default. Let's assumes that one who
enable it knows how to delete such inodes.
For example like follows:
find $TEST_PATH -exec chattr -i -a {} \;
rm -rf $TEST_PATH

It is very hard to predict runtime for fsstress. In many cases it
is useful to give test to run a reasonable time, and then kill it.
But currently there is no reliable way to kill test without leaving
running children.
This patch add sanity cleanup logic which looks follow:
- On sigterm received by parent, it resend signal to it's children
- Wait for each child to terminates
- EXTRA_SANITY: Even if parent was killed by other signal, children
will be terminated with SIGKILL to preven staled children.
So now one can simply run fsstress like this:
./fsstress -p 1000 -n999999999 -d $TEST_DIR &
PID=$!
sleep 300
kill $PID
wait $PID

Currently the only way to log fsstress's output is to redirect it's shared
stdout to pipe which is very painfull because:
1) Pipe writers are serialized via i_mutex so we waste cpu-cores power on stupid
sinchronization for loging purpose, instead of hunting real race conditions,
and bugs inside file system.
2) Usually output is corrupted due to luck of sychronization on shared stdout.
Since fsstress's children operate on independend paths, let's just open didicated
log file for each child and simply avoid useless sycnhronization.

Before punching a hole in a file, TRIM_OFF_LEN() calls
TRIM_OFF_LEN() in order to make sure the offset and size
used are in a reasonable range. But currently the range
it's limited to is maxfilelen, which allows the offset
(and therefore offset + len) to be beyond EOF.
Later, do_punch_hole() ignores any request that starts beyond
EOF, so we might as well limit requests to the file size.
It appears that a hole punch request that starts within a
file but whose length extends beyond it is treated simply
as a hole punch up to EOF. So there's no harm in limiting
the end of a hole punch request to the file size either.
Therefore, use TRIM_OFF_LEN() to put both the the offset
and length of a request within the file size for hole
punch requests.
