| |
Hi, These patches are in no way an attempt to push this for inclusion, but instead a bit of grunt work to keep it current. However i would very much so like see it included in mainline.
- sync against 2.5.59 - add additional cpu_online check in i386 cpu_up to differentiate between boot and runtime offlined/onlined cpus. - fix cpu online show/store oops due to changes in struct device_attribute - added CPU_DEAD case for mm/slab.c to fix memory leak (double allocation) and added stop_cpu_timer() - added CPU_DEAD case for RCU, here we clear the cpu's rcu_data and kill its tasklet. Added rcu_offline_cpu() - added CPU_DEAD case for fs/buffer.c (suggestion from Andrew Morton, bugs from me)
Tested on a 4way i386 with cpu offline, online whilst doing make -j4 bzImage. It is possible to induce what appear to be deadlocks but i am working through those as i go along. Rusty is there anything i can do to get this merged with what you currently have?
