If I run the following:
sleep inf &
pgrep -a sleep
I'd expect a result like:
./busybox pgrep -a sleep
3955 sleep inf
(That's the result I get from procps's pgrep.)
But prior to this patch, I'd actually get:
./busybox pgrep -a sleep
3955 sleep
This happened because the processes' full argv was only being read if
-f was passed, but -a also needs it to be read so it can print it.
