OK, so the problem seems the inode in question has the INLINE_DATA
flag set, but i_blocks is non-zero. And it looks like the data was
actually stored in an exernal data block, and the in-line xattr wasn't
present.
e2fsck should be checking and complaining if this is the case. If
not, it's a bug in e2fsck.
And the kernel certainy shouldn't be BUG'ing when it comes across
what is clearly a case of file system corruption.
Cheers,

Hello,
Perhaps I am wrong, but as the inode has a file ACL, the blockcount should be
different from 0?
So it seems valid on this point. Or is there something that prevent inlined file
to have ACL?
Regards,
Damien
