Subject[PATCH -next 0/3] scsi/fcoe: Play nicer with PREEMPT_RT
Date
Hi,

The following are the result of trying to get rid of the out-of-tree
equivalent[1].

Patches 1 and 2 remove the actual scheduling while atomic scenarios.

Patch 3 could be considered optional because afaict the stats do not
actually have blocking calls while having preemption disabled. But
from an RT perspective it's still beneficial as the region remains
preemptible.

Compile tested only.

Thanks!
