The intention is to have YAFFS doing attribute handling just the same as any 
other fs. Any wierdo behaviour like you report here is a bug.

YAFFS does jump through a few hoops because it does not use inodes and 
dentries internally, but that is supposed to be sorted out by the YAFFS fs 
layer.

Can anyone confirm these problems on the same or other Linux versions?
