ad795510d9 mdev: if a "future" mdev.seq is seen, do not overwrite it with ours
This was seen to happen if two mdevs are run in parallel,
mdev.seq is empty, and the "newer" one manages to write it first.

a3f326cd66 swapon/swapoff: size reduction, cleanup, fixes, improvements
1) real swapon/swapoff handles also devices on the commandline with -a;
2) xstat(device)  in  swap_enable_disable aborts on error when cycling through
   fstab so some devices  are not handled;
3) duplicated code for ENABLE_FEATURE_SWAPON_DISCARD and
   ENABLE_FEATURE_SWAPON_PRI was moved to functions.
4) silence some error messages with -a;
5) minor cleanups and code refactoring reduced the size as per bloat-check:
6) I also added support for /proc/swaps handling to swapoff:
"When the -a flag is given, swapping is disabled on all known  swap  devices
 and  files  (as  found  in  /proc/swaps  or /etc/fstab)."
So now swapoff first cycles through  /proc/swaps and then through fstab
to swapoff all devices.

0ed5f7aacd use [s]rand(), not [s]random()
rand() is the most standard C library function,
and on uclibc they are the same. I guess
they are the same in most todays' libc...

"Trimming" your NAND/eMMC storage will restore the write performance

c3cf1e30a3 mdev: use $DEVNAME in uevent sysfs file for device node name
516530c932 uses $DEVNAME variable
for device node name. This is fine, but only works for hotplugging,
"mdev -s" will behave differently when DEVNAME and basename(path)
differ.

This patch extracts the DEVNAME from the uevent sysfs file in
make_device(), thus works for hot- and coldplugging; so using
the environment DEVNAME on hotplug events is no longer necessary.
