Will the same apply to e.g. sd_index_ida in drivers/scsi/sd.c or iscsi_sess_ida in drivers/scsi/scsi_transport_iscsi.c? If no, why not? One doesn't generally expect to have to free global variables.

Hi Konrad I encountered a bug when trying to bring offline a cpu then online it again in HVM. As I''m not very familiar with HVM stuffs I cannot come up with a quick fix. The HVM DomU is configured with 4 vcpus. After booting into command prompt, I do following operations. # echo 0 > /sys/devices/system/cpu/cpu3/online # echo 1 > /sys/devices/system/cpu/cpu3/online With

Hi, The following patches fix couple of memory leaks in the virtio and remoteproc cores when using these as modules, and going through a cycle of insmod and rmmod with at least a device registered with the corresponding cores in between. I ran into this on our downstream product kernels on both 3.14 and 4.1 based kernels, and should apply to the latest kernel as well. Patches can be picked up
