Subject: [PATCH] 2.4: export scheduling information from /proc
Date: 06 Oct 2002 15:45:17 -0400 [thread overview]
Message-ID: <1033933518.742.4470.camel@phantasy> (raw)
Menacing Marcelo,
Attached patch exports scheduling policy and real-time priority from
/proc/<pid>/stats.
This code is in 2.4-ac and 2.5.
This does _not_ break previous versions of procps -- there is no harm
and it is fully backward compatible. New versions, starting with 2.0.8,
can parse this information.
Patch is against 2.4.20-pre9. Please, apply.
Robert Love
