Convert macro STRIPE_SIZE, STRIPE_SECTORS and STRIPE_SHIFT to RAID5_STRIPE_SIZE(), RAID5_STRIPE_SECTORS() and RAID5_STRIPE_SHIFT(). This patch is prepare for the following adjustable stripe_size. It will not change any existing functionality. Signed-off-by: Yufen Yu Signed-off-by: Song Liu

md: raid5-cache: Remove set but unused variable

md/raid5-cache: clear MD_SB_CHANGE_PENDING before flushing stripes

2020-07-15T06:01:31Z

In recovery, if we process too much data, raid5-cache may set MD_SB_CHANGE_PENDING, which causes spinning in handle_stripe(). Fix this issue by clearing the bit before flushing data only stripes. This issue was initially discussed in [1]. [1] https://www.spinics.net/lists/raid/msg64409.html Signed-off-by: Song Liu

md/raid5: fix 'out of memory' during raid cache recovery

2019-01-28T19:44:40Z

This fixes the case when md array assembly fails because of raid cache recovery unable to allocate a stripe, despite attempts to replay stripes and increase cache size. This happens because stripes released by r5c_recovery_replay_stripes and raid5_set_cache_size don't become available for allocation immediately. Released stripes first are placed on conf->released_stripes list and require md thread to merge them on conf->inactive_list before they can be allocated. Patch allows final allocation attempt during cache recovery to wait for new stripes to become availabe for allocation.

md: Avoid namespace collision with bitmap API

2018-08-01T22:49:39Z

bitmap API (include/linux/bitmap.h) has 'bitmap' prefix for its methods. On the other hand MD bitmap API is special case. Adding 'md' prefix to it to avoid name space collision. No functional changes intended. Signed-off-by: Andy Shevchenko Acked-by: Shaohua Li Signed-off-by: Dmitry Torokhov
