Hello:

This patch was applied to netdev/net-next.git (main)
by Jakub Kicinski [off-list ref]:

gro_cells allocates a per-CPU struct gro_cell with per-CPU queues
(cell->napi_skbs), per-CPU local_lock_t (cell->bh_lock), and per-CPU
napi_struct (cell->napi). On !CONFIG_PREEMPT_RT, local_lock_t only
provides lockdep annotation (and is a complete no-op when
CONFIG_DEBUG_LOCK_ALLOC is disabled), relying on per-CPU locality and
disabled BH context for mutual exclusion; it does not provide cross-CPU
synchronization.
