UAPI: include <asm/byteorder.h> in linux/raid/md_p.h raid1: Rewrite the implementation of iobarrier. raid1: Add some macros to make code clearly. raid1: Replace raise_barrier/lower_barrier with freeze_array/unfreeze_array when reconfiguring the array. raid1: Add a field array_frozen to indicate whether raid in freeze state. md: Convert use of typedef ctl_table to struct ctl_table md/raid5: avoid deadlock when raid5 array has unack badblocks during md_stop_writes. md: use MD_RECOVERY_INTR instead of kthread_should_stop in resync thread. md: fix some places where mddev_lock return value is not checked. raid5: Retry R5_ReadNoMerge flag when hit a read error. raid5: relieve lock contention in get_active_stripe() raid5: relieve lock contention in get_active_stripe() wait: add wait_event_cmd() md/raid5.c: add proper locking to error path of raid5_start_reshape. md: fix calculation of stacking limits on level change. raid5: Use slow_path to release stripe when mddev->thread is null |
