From: Li Nan <linan122@xxxxxxxxxx> Changes in v5: - add patches 1-4 to clean up md_ioct(), pathc 4 can help us clean up local variable 'clear_md_closing'. - in patches 5 and 7, clean up local variable 'clear_md_closing'. By the way, md_ioctl() is not readable now, I wanna to re-write it later to make it only have one 'switch' like other drivers. Li Nan (8): md: merge the check of capabilities into md_ioctl_valid() md: changed the switch of RAID_VERSION to if md: clean up invalid BUG_ON in md_ioctl md: return directly before setting did_set_md_closing md: Don't clear MD_CLOSING when the raid is about to stop md: factor out a helper to sync mddev md: sync blockdev before stopping raid or setting readonly md: check mddev->pers before calling md_set_readonly() drivers/md/md.c | 149 ++++++++++++++++++++++++++---------------------- 1 file changed, 80 insertions(+), 69 deletions(-) -- 2.39.2
