4K block size question

[Artem B. Bityuckiy]

Hello,

In case of 2MiB NAND flash (with 256-byte page) the sector size is 4KiB. 
The JFFS2 virtual block size is also 4KiB.

The size of pristine node is 4KiB data + node header. So, in 
uncompressed form, the pristine node can't fit into JFFS2 block if the 
compression is disabled. So, how does JFFS2 work on such flash :-) ?

Thanks.
