Aside of in_interrupt() being deprecated because it's not providing what it claims to provide, this check would paper over illegitimate callers. The functions invoked from t4_sge_stop() contain already warnings to catch invocations from invalid contexts. Remove it. Signed-off-by: Thomas Gleixner Cc: Vishal Kulkarni Cc: "David S.
