Subject: [SCSI] fcoe: use kthread_create_on_node
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5c609ff937a91cf09b1f8d7612cd00bc046c27f7;p=linux-beck.git

[SCSI] fcoe: use kthread_create_on_node

Since fcoe_percpu_thread_create() creates percpu kthread, it makes sense
to use kthread_create_on_node() to get proper NUMA affinity for kthread
stack.
