Hi everybody
I'm newbie of busybox. 
I'm running it on my sh-3 7709a bsed board.
When  I execute mount (remount ) of root filesystem, the system  tells me 
somwthign on my filesystem is wrong so I should run fsck. Busybox doesn't 
have fsck,  so few questions:
1) Why I have this messages form the system
"VFS: busy inodes on changed media."
I read this is in /fs/block_dev.c

2) Why this form /fs/buffer.c
"invalidate: dirty buffer\n"

3) why this form /fs/ext2/super.c
		printk ("EXT2-fs warning: mounting unchecked fs, "
			"running e2fsck is recommended\n");


Thanks a lot.
