* taskset: fix for PID longer than 12 charsDenys Vlasenko2021-06-201-2/+3
| | | | | | | | | | | | Should we validate that PID is a number for "taskset -ap PID"? We don't actually need it, and pathological input like "../../DIR_WITH_LOTS_OF_PIDS" can only cause "taskset"ing of many pids. Which is something user can do anyway. function old new delta taskset_main 190 181 -9 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | If logging to stderr and/or syslog the -v option can be given one or more times to increase the log verbosity. If mdev is used as hotplug helper the log level is fixed set to 2 if mdev.log is found an appended because there is no possiblity to pass arguments to the hotplug helper.

* mdev: add syslog logging modeJan Klötzke2020-11-221-6/+18
| | | | | | | | | | | | If mdev is run as daemon it should be possible to forward the debug messages to syslog. This feature might be useful if mdev is run with -s during boot too. OTOH it makes no sense for the daemon to log to mdev.log. This can be handled by a syslog daemon way better. If the daemon stays in the foreground due to -f, the messages are still written to stderr as before.
