Hi Akira,
I am consistently getting -EBADF while trying out e4defrag and it
fails with below error.
/home/mkatiyar/e2fs-git/e2fsprogs/misc> ./e4defrag -v /tmp/ohsm/mntdir/f1
ext4 defragmentation for /tmp/ohsm/mntdir/f1
[1/1]/tmp/ohsm/mntdir/f1: 0%
Failed to defrag:Bad file descriptor [ NG ]
Success: [0/1]
Below patch fixes the issue for me, though I am not sure if this is
the right fix to open the source file in readwrite mode or fix the
ext4 ioctl part.
Open the source file in read write mode to avoid failures from EXT4_IOC_EXT_MOVE
