Subject: ipc/shm.c:494:18: warning: unused variable ‘hs’ [-Wunused-variable]
Date: Wed, 8 May 2013 16:34:11 +0200 [thread overview]
Message-ID: <20130508143411.GD30955@pd.tnic> (raw)
Hi,
looks like this warning came in with
af73e4d9506d3b797509f3c030e7dcd554f7d9c4 and fires in the
# CONFIG_HUGETLB_PAGE is not set
case because
struct hstate *hs = hstate_sizelog((shmflg >> SHM_HUGE_SHIFT)
& SHM_HUGE_MASK);
becomes
struct hstate *hs = ((void *)0)
due to
#define hstate_sizelog(s) NULL
Hmmm, I don't have a quick solution off the top of my head from staring
at the code.
