Subject: [PATCH 12/22] ext4_add_entry(): ->d_name.len is never 0
That bogosity goes back to the initial merge of ext3. Once upon a time
ext2 used to have a similar check; that got taken out during the switch
to page cache (June 2001). ext3 got merged into mainline 5 months later,
still using buffer cache for directories; removal of the pointless check
in ext2 should've been done as a separate patch, but it hadn't been,
so that thing got missed...
