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.

"rmmod OUT_OF_TREE_MODULE" was not working, because module is not in depmod file.
In general, rmmod doesn't need scanning, it simply unloads every argv[i].

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.

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.

(re-sending this as it got ignored completey and the format of the

anything else I can do to get this trivial fix applied)
for telnetd to work, we only need CONFIG_UNIX98_PTYS to be enabled

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.

We wanted to detect when tv_sec = unsigned1 - unsigned2
underflows by looking at tv_sec's sign. But if tv_sec
is long and it is wider than unsigned, we get unsigned -> long
conversion which is in this case never negative.

This fixes a regression introduced with commit 78854520 (modprobe:
revert checking for /, stop doing basename() on modprobe args,
2015-01-01) that broke modprobe options stored in /etc/modprobe.conf and
/etc/modprobe.d/*.conf.
This also fixes modprobe -r

If the :r command is used to read a file after the last line of the
buffer the last line of the buffer and the first line of the file
are joined. An extra blank line appears at the end of the buffer.

Starting vi with no filename on the command line gives the status message
"'(null)' Bad address" instead of "- No file 1/1 100%".

message "'new.txt' No such file or directory" instead of "- new.txt 1/1 100%"
