Subject: linux-next: build warning after merge of the device-mapper tree
Date: Mon, 11 Dec 2017 13:05:34 +1100 [thread overview]
Message-ID: <20171211130534.6ab6e415@canb.auug.org.au> (raw)
Hi all,
After merging the device-mapper tree, today's linux-next build (powerp
ppc64_defconfig) produced this warning:
drivers/md/dm.c: In function '__send_changing_extent_only':
drivers/md/dm.c:1365:45: warning: 'ti' may be used uninitialized in this function [-Wmaybe-uninitialized]
num_bios = get_num_bios ? get_num_bios(ti) : 0;
^
Introduced by commit
aecefd4919de ("dm: fix __send_changing_extent_only() to send first bio and chain remainder")
This looks particularly bad :-(

Cheers,
Stephen Rothwell
