| H A D | blk-stat.c | diff e11d80a849e010f78243bb6f6af7dccef3a71a90 Tue Sep 01 13:52:32 CDT 2020 Tejun Heo <tj@kernel.org> blk-stat: make q->stats->lock irqsafe
blk-iocost calls blk_stat_enable_accounting() while holding an irqsafe lock
which triggers a lockdep splat because q->stats->lock isn't irqsafe. Let's
make it irqsafe.
