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

Hi all,

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

fs/direct-io.c: In function 'sb_init_dio_done_wq':
fs/direct-io.c:557:2: warning: value computed is not used [-Wunused-value]

This is:

	cmpxchg(&sb->s_dio_done_wq, NULL, wq);

Introduced by commit 7b7a8665edd8 ("direct-io: Implement generic deferred
AIO completions").

Cheers,
Stephen Rothwell                    sfr@...b.auug.org.au
