Tests the RWF_NOWAIT flag so the I/O returns immediately with -EAGAIN
on a new file since it requires block allocation.
It creates a file, syncs it, and overwrites the file with RWF_NOWAIT.
This should succeed.
Finally, read the contents to make sure the overwrite is successful.
Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.com>
Changes since v1:
- Fix testdir name
- use of $XFS_IO_PROG instead of xfs_io
- check pwrite accepts -N

Wrong test description? It seems for generic/471.

I think this test can be run on $TEST_DEV directly, so _require_test
here and do all the tests in $TEST_DIR would be fine.

Hmm, any reason using 128M block size? I'm afraid it will cause problems
when memory is low.

This looks fragile to me, at least this needs a big comment.

From: Goldwyn Rodrigues <rgoldwyn@suse.com>
Getting an error midway through a direct write would return an error
and the error-code is returned in the write() call. However, partial
data is over-written during the call.
This tests simulates the ENOSPC error to check for partial direct
write consistency.
Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.com>
Changes since v1:
- Check for option pwrite -O
- Create a 200M file instead of multiple 40M files.

No need to umount $SCRATCH_MNT, _require_scratch will do it for you.

No need to remove $testdir here, scratch_dev is freshly created.

Hmm, I can see that "-O" requires bigger block size in this case. Then
how about reserving some space first and fill the rest then remove the
reserved file? So we have a fixed amount of space to do the test. e.g.
# reserve 2m space first
$XFS_IO_PROG -fc "pwrite 0 2m" $testdir/reserve
# fill the rest of the fs
$XFS_IO_PROG -fc "pwrite 0 320m" $testdir/fill
# remove the reserve file to get space free
rm -f $testdir/reserve
...
$XFS_IO_PROG -dc "pwrite -O -S 0xcd -V 1 -b 4m 0 4m" $testdir/partial
...

I think we'd need some comments on why direct I/O is needed for "-N"
option. And better to declare 'opts' as a local variable.

"Operation not supported" case above, it's a bit confusing why the two
