'df' reports a wrong space calculation
What's wrong about the space calculation?
Please give the 'df' command that you ran, its faulty output, and also
the output of 'strace' applied to the 'df' command that you ran. For
example, on my machine, 'strace df' outputs the line:
statfs("/tmp", {f_type=TMPFS_MAGIC, f_bsize=4096, f_blocks=1018122,
f_bfree=1007348, f_bavail=1007348, f_files=1018122, f_ffree=1018073,
f_fsid={val=[0, 0]}, f_namelen=255, f_frsize=4096,
f_flags=ST_VALID|ST_NOSUID|ST_NODEV}) = 0
and those are the numbers that 'df' uses to calculate what it should
output. If those numbers are wrong, df's output will be wrong but it's
not df's fault - it's the kernel or btrfs or whatever. If those numbers
are right but df's output is wrong, then df is at fault.
