Re: [Yaffs] Yaffs memory full handling

yaffs_freespace() provides a rougher guess of the space. You could use
that, but clearly there are threading issues if you do it that way.

yaffs_write() will return the number of bytes written.

ret = yaffs_write(...);
if ( ret != write_size)
SetMemFullError();
