Yep, it's added, thanks. I'm not entirely right the error handling is
completely correct in this function; in particular, if we fail after
this point in the function, and we've already changed the status of
EXT4_STATE_XATTR flag, but then we fail due to some error (maybe an
I/O error), it's not clear the cleanup section is properly unwinding
all of the side effects made so far in this function.
Still, adding the error check clearly makes the code better than it
was before, so I've added it to the ext4 patch queue.
