f2fs: fix wrong calculation on f_files in statfs
In f2fs_statfs(), f_files should be the total number of available inodes
instead of the currently allocated inodes.
So, this patch should resolve the reported bug below.
Note that, showing 10% usage is not a bug, since f2fs reveals whole volume size
as much as possible and shows the space overhead as *used*.
This policy is fair enough with respect to other file systems.
<Reported Bug>
(loop0 is backed by 1GiB file)
$ mkfs.f2fs /dev/loop0
F2FS-tools: Ver: 1.1.0 (2012-12-11)
Info: sector size = 512
Info: total sectors = 2097152 (in 512bytes)
Info: zone aligned segment0 blkaddr: 512
Info: format successful
$ mount /dev/loop0 mnt/
$ df mnt/
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/loop0 1046528 98312 929784 10%
/home/zeta/linux-devel/mtd-bench/mnt
$ df mnt/ -i
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/loop0 1 -465918 465919 - /home/zeta/linux-devel/mtd-bench/mnt
Notice IUsed is negative. Also, 10% usage on a fresh f2fs seems too
much to be correct.
