Hi Shaohua,
After merging the md tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
drivers/md/md.c: In function 'md_run':
drivers/md/md.c:5449:21: error: too few arguments to function 'bioset_create'
mddev->sync_set = bioset_create(BIO_POOL_SIZE, 0);
^
In file included from include/linux/blkdev.h:20:0,
from drivers/md/md.c:49:
include/linux/bio.h:375:24: note: declared here
extern struct bio_set *bioset_create(unsigned int, unsigned int, int flags);
^
Caused by commit
5a85071c2cbc ("md: use a separate bio_set for synchronous IO.")
interacting with commit
011067b05668 ("blk: replace bioset_create_nobvec() with a flags arg to bioset_create()")
from the block tree.
I applied the following merge fix patch:
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>

Subject: [PATCH] md: fix up for "blk: replace bioset_create_nobvec() with a
flags arg to bioset_create()"
