Just compare the mes in yaffs_linux.c with a normal linux filesystem.
All that gross magic nfsd detection in readdir could have been removed
long ago.  ->readlink should not be implemented by a normal filesystem
but use generic_readlink, the fs-specific inode should embedd the vfs
inode instead of requiring two allocations, tons of useless function
pointer indirections like sb_dirty_fn and the put_super_fn really must
go away.  The procfs interfaces should be replaced by something saner,
the insane amount of ad-hoc tracing crap should be replaced by much
less strategically placed trace events, and all those stupid compile
time options have absolutely no business at all beeing there for a
filesystem - remember you can get media from all over the place.
If you can't encode these difference in your on-disk format it has
absolutely no business going into mainline with this format.

And last but not least there's no way we'll merge a filesystem with a
global mutex and all kinds of hacky release and reaquire semantics
these days.  I really think you need to get back to the drawing board.
