Nobody.
Because there is no bugreports.

If you mean the "todo for inclusion", then no.

Reiser4 has only one technical issue. It can
be resolved only by very experienced people.

this is not good: a file system should respond on sync (1).

you might want to ask such question _before_ sending patches to akpm. 

BTW excellent comment, what is not clear?

/**
 * reiser4_sync_inodes - sync_inodes of super operations
 * @super:
 * @wbc:
 *
 * This method is called by background and non-backgound writeback. 
Reiser4's
 * implementation uses generic_sync_sb_inodes to call reiser4_writepages for
 * each of dirty inodes. Reiser4_writepages handles pages dirtied via shared
 * mapping - dirty pages get into atoms. Writeout is called to flush some
 * atoms.
