Thanks for the debugging. So the problematic files were regular files that lead
pretty simple life - no references from unexpected places or so. What catches
my eye is that inode numbers are surprisingly small (22, 12, 13; in your
original report 17, 15). Since normal inode numbers start by 11 and that is
usually taken by lost+found, numbers 12 and 13 are as small as they can get. I
suppose this is a filesystem dedicated for the build, isn't it? And the files
making problems are created as a first files on that filesystem in its root
directory. Any idea what those files are?

Another thing: i_count=2501 for inode 22 is absurdly high. We'd have to leak
references really heavily for that file.

I've checked the code in writeback_inodes_wb() and wait_sb_inodes() but
reference counting there looks fine. So I have no clue what's going on right
now. Anyway, adding Jens to CC just in case it rings a bell to him.
