Hi Greg,

After merging the final tree, today's linux-next build (powerpc
allnoconfig) produced this warning:

lib/kobject_uevent.c:86: warning: 'kobj_bcast_filter' defined but not used

Introduced by commit 5f71a29629b4717445f8b7f5fb8f50c2d262b68e ("kobj:
Send hotplug events in the proper namespace") from Linus' tree.

Thanks, someone already sent me a patch for this and I'll queue it up
next week.

linux-next: build warning after merge of the final tree (Linus' tree related)

Hi all,

After merging the final tree, today's linux-next build (arm defconfig)
produced this warning:

ipc/shm.c: In function 'newseg':
ipc/shm.c:494:18: warning: unused variable 'hs' [-Wunused-variable]

Introduced by commit af73e4d9506d ("hugetlbfs: fix mmap failure in
unaligned size request") in Linus' tree.

Did the "[akpm@linux-foundation.org: fix warning when
CONFIG_HUGETLB_PAGE=n]" part get dropped?  Or was that something else?

In my original post, 2 auto variables hs were used both in newseg() and
sys_mmap_pgoff(), and Andrew fixed only one in sys_mmap_pgoff().
hs remains in newseg(), so it fires warning in linux-next.
Hours ago Li suggested another fix of af73e4d9506d and it implicitly
fixes this warning.
