748fb60f27 arping: fix iface name in error messages
arping: interface eth0 not found: No such device
                  ^^^^

This is because error template is formed before parsing command line arguments,
so it always uses default interface name "eth0".

1fd844267c modprobe-small: if concurrent module load did not succeed, wait
usecase:
two sd cards are being mounted in parallel at same time on dual core. example
modules which are getting loaded is  nls_cp437. While one module is being
loaded , it makes state in /proc/modules as 'coming' and then starts doing its
module init function (in our case - registering nls). meanwhile on other core,
if modprobe returns that is has already been loaded, then it will continue
and search for the nls list which is not yet finished from first module init.
This fails resulting in not mounting sd card.

782ee2aa0e libbb/loop: don't try to re-use existing loop device
loopinfo.lo_file_name is not enough to uniquely identify a file on a system with
multiple mount namespaces.  We could conceivably change this to dedup on
(lo_rdevice, lo_inode), but, as the comment above the deleted code notes, this
whole approach of reusing devices is racy anyway, so it seems better to stop
doing it entirely.

7f7ade1964 gzip: do not store timestamp in gzip header
Storing the original file's modification time in the output file is
harmful (precludes deterministic results) and unlike official gzip,
the busybox version provides no way to suppress this behavior; the -n
option is silently ignored. Rather than trying to make -n work, this
patch just removes the timestamp-storing functionality. It should be
considered deprecated anyway; it's not Y2038-safe and gunzip ignores
it by default.

Per RFC 1952, 0 is the correct value to store to indicate that there
is no timestamp.

ff3f3accc6 ntpd: get rid of G.initial_poll_complete
This speeds up syncing - now happens only just
two replies from a peer. Especially useful for "ntpd -q".
Shouldn't have ill effects: if we chose a bad peer,
we will discover it later and switch to another one.

The code is even smaller this way.
