This looks like an abuse of the "one entry one value" rule for sysfs.
Perhaps this should be a directory /sys/class/block/defined_triggers/
and separate files under that for foo, bar, and baz?  That would probably
make reference counting a lot easier as well....

Indeed it is.

Funny that you should mention using a subdirectory.  I originally wanted
to put all of the trigger-related stuff into
/sys/class/block/led_triggers/, but I couldn't find any API to create a
subdirectory for *class* attributes (only for device attributes), nor do
I see any such subdirectories on my system.

  # find /sys/class -type d | egrep '^/sys/class/[^/]+/'
  (no output)

Is is possible to create subdirectories for class attributes?
