[Yaffs] [Yaffs-archive] YAFFS checkins

[Charles Manning]

Hi YAFFSERs

Thanks to Stephan for pointing out the holes in the du reporting. I have just 
patched yaffs_fs.c with something that  should be right. Comments/feedback 
appreciated. NB though: du is at best an approximation of actual disk in use. 
It does not take into account reserved space etc. 

Wookey has checked in a submitted path in yaffs_guts to do with the handling 
of yaffs_DeleteChunk(). While the patch should be benign (ie won't break 
YAFFS), I think the patch is based on a misunderstanding of the way NAND 
works and do not think it is required and will slow things slightly. I am 
discussing the issue with the submitter and Wookey to resolve one way or the 
other. 

Regards
