[PATCH 14/20] Make proc_flush_task() actually from entries from multiple namespaces
- From: xemul@xxxxxxxxxx
- Date: Fri, 10 Aug 2007 15:48:18 +0400
This means that proc_flush_task_mnt() is to be called for many proc
mounts and with different ids, depending on the namespace this pid
is to be flushed from.
