Package: libpam-runtime
Version: 0.79-1
Followup-For: Bug #326555
This is my backport of the version of the rtlimits patch now merged in
the linux-pam CVS. Differences to previous patch are:
- item name in limits.conf is "rt_prio" rather than "rt_priority"
- nice value goes from -20 to 19, rather than 0 to 39.
- do not define RLIMIT_FOO values, but rather get them from kernel
headers (where available), and protect uses of them with #ifdef
