As source code shows , many files have single and multi two different version , i.e. yaffs_mtdif2_multi.c and yaffs_mtdif2_single.c , yportenv_multi.h and yportenv_single.h.

there functions look same.

So what’s the real different of the two different? And if don’t use yaffs with OS,and I could comment these files?

Wish anyone’s help.
