Sometimes the user wants to know minimum size for dirty (e.g. mounted) filesystems. In this case, resize2fs -P will require calling e2fsck -f, while "in general, it is not safe to run e2fsck on mounted filesystems".

Since resize2fs -P does not modify filesystem, we force it to display (probably approximate) minimum size. --- daemon/ext2.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
