f2fs-tools: bump to version 1.4.1

Subject: [PATCH] configure: add check for fallocate

We need to check for fallocate() rather than just linux/falloc.h +

FALLOC_FL_PUNCH_HOLE since in uClibc we've got both but still not

fallocate() itself since it's only implemented in newer unreleased

versions.

Status: sent upstream.

Subject: [PATCH] mkfs.f2fs: possible endianes bug in mkfs.f2fs roll-forward

 speed

I might found a bug in mkfs.f2fs. while experimenting with f2fs on my big

endian MIPS32 device (platform lantiq, 14.07-rc3, uclibc).

I ran into an issue that mkfs.f2fs, was not able to format block devices if I

did not specify the sector count manually.

I hunted it down to lib/libf2fs.c.

After I found that the detected sector count equals to the wanted sector count

shifted left (32+9) times.

I found two issues:

Firstly it uses ioctl BLKGETSIZE, which writes to an uint32_t the size of the

device.

As c->total_sectors is of type uint64_t, the value is written in to the first

4 bytes.

That explained the left shift of 32 bits.

Secondly BLKGETSIZE determines the size of the device in bytes (AFAIK, learned

by observation).

In the first branch of the if-block patched below, the c->total_sectors is

calculated by

  c->total_sectors = stat_buf.st_size / c->sector_size;

The else branch omits the devision. sector_sice is mostly 512, that explained

the left shift by 9 bytes.

 * fixes sector count calculation

 * uses BLKGETSIZE64 if avail
