Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/shli/md
Pull MD update from Shaohua Li: - fixed deadlock in MD suspend and a potential bug in bio allocation (Neil Brown) - fixed signal issue (Mikulas Patocka) - fixed typo in FailFast test (Guoqing Jiang) - other trival fixes * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/shli/md: MD: fix sleep in atomic MD: fix a null dereference md: use a separate bio_set for synchronous IO. md: change the initialization value for a spare device spot to MD_DISK_ROLE_SPARE md/raid1: remove unused bio in sync_request_write md/raid10: fix FailFast test for wrong device md: don't use flush_signals in userspace processes md: fix deadlock between mddev_suspend() and md_write_start()
