[PATCH v2 0/4] net: drop netif_attrmask_next*()

From: Yury Norov
Date: Thu Oct 13 2022 - 19:44:19 EST


netif_attrmask_next_and() generates warnings if CONFIG_DEBUG_PER_CPU_MAPS
is enabled. It is used in a single place. netif_attrmask_next() is not
used at all. With some rework of __netif_set_xps_queue(), we can drop
both functions, switch the code to well-tested bitmap API and fix the
warning.

v1: https://lore.kernel.org/netdev/20221002151702.3932770-1-yury.norov@xxxxxxxxx/T/
v2: Fix missed bitmap initialization in patch #3.

Yury Norov (4):
net: move setup code out of mutex in __netif_set_xps_queue()
net: merge XPS_CPU_DEV_MAPS_SIZE and XPS_RXQ_DEV_MAPS_SIZE macros
net: initialize online_mask unconditionally in __netif_set_xps_queue()
net: fix opencoded for_each_and_bit() in __netif_set_xps_queue()
