Subject: acct: real_parent ppid
X-Git-Tag: v2.6.24-rc8~72
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=b59f8197c5ddd0d5d74b663650be5449dacd34aa;p=linux-2.6-omap-h63xx.git

acct: real_parent ppid

The ac_ppid field reported in process accounting records
should match what getppid() would have returned to that
process, regardless of whether a debugger is attached.
