This patch introduces a new testcase to test some small truncations to check
inline_data and its cached data are truncated correctly at the same time.

The inline_data feature was introduced in ext4 and f2fs as follows.
 ext4 : http://lwn.net/Articles/468678/
 f2fs : http://lwn.net/Articles/573408/

The basic idea is embedding small-sized file's data into relatively large
inode space.
In ext4, up to 132 bytes of data can be stored in 256 bytes-sized inode.
In f2fs, up to 3.4KB of data can be embedded into 4KB-sized inode block.

_scratch_remount without any options is a no-op. Should be
_scratch_cycle_mount?

Seems the output is corrupted. Is it missing a "00000030  00 00" line?

[root@localhost xfstests]# truncate -s 50 testfile
[root@localhost xfstests]# hexdump -C testfile

I tested with ext4 (with inline_data enabled and disabled), xfs and
btrfs, they all fail in the same way.

Hmm, in my case, all the filesystems show without that line.

It seems that hexdump gives that differently. When I tested od, I could get this
from all the filesystems.

od /mnt/test/testfile
0000000 000000 000000 000000 000000 000000 000000 000000 000000
*
0000060 000000
0000062

Let me change the patch to use od.

Thanks,

+# Test some small truncations to check inline_data and its cached data are
+# truncated correctly at the same time.
+#
+# The inline_data feature was introduced in ext4 and f2fs as follows.
+#  ext4 : http://lwn.net/Articles/468678/
+#  f2fs : http://lwn.net/Articles/573408/
+#
+# The basic idea is embedding small-sized file's data into relatively large
+# inode space.
+# In ext4, up to 132 bytes of data can be stored in 256 bytes-sized inode.
+# In f2fs, up to 3.4KB of data can be embedded into 4KB-sized inode block.
