Is it missing a "00000030 00 00" line? 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.

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.
