Hi Andrew, Today's linux-next merge of the akpm tree got a conflict in kernel/fork.c between commit touching paths: ("fork: call complete_vfork_done() after clearing child_tid and flushing rss-counters") from Linus' tree and commit "mm: correctly synchronize rss-counters at exit/exec" from the akpm tree. Just context changes. I fixed it up (see below) and can carry the fix as necessary. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au diff --cc kernel/fork.c index 095a951,30e9ee8..0000000 --- a/kernel/fork.c +++ b/kernel/fork.c @@@ -808,11 -811,12 +808,19 @@@ void mm_release(struct task_struct *tsk } /* + * Final rss-counter synchronization.
