I forgot to test that patch with that option disabled. Honestly, I'm more and more uncertain about how useful (disabling) that option is ... In any case, one question about the present patch: I didn't add any hash for the commit that this patch fixes, because, if I'm not mistaken, the hash that that commit will have in mainline is not yet defined. I hope this is the right way to go. Thanks, Paolo Paolo Valente (1): block, bfq: compile group put for oom queue only if BFQ_GROUP_IOSCHED is set block/bfq-iosched.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) -- 2.15.1
