My point was commit 85e0cbbb8a made blk_debugfs_root non-null always now
when debugfs is enabled for both request-based block drivers and for
make_request block drivers (multiqueue). My reading is that with your
patch blk_debugfs_root will not be created for request-based block
drivers.
Hi Luis,
The empty version of blk_mq_debugfs_init() in my patch is only selected
if CONFIG_BLK_DEBUG_FS=n. I think that my patch preserves the behavior
that /sys/kernel/debug/block/ is created independent of the type of
request queues that is created. Am I perhaps misunderstanding your feedback?
Thanks,
Bart.
