commit 0c069781ddfa4e31c169a8eced1ee90b8929d522 upstream. Signed-off-by: Daniel Hill Signed-off-by: Kent Overstreet Signed-off-by: Greg Kroah-Hartman

bcachefs: Extra kthread_should_stop() calls for copygc

2023-11-29T03:58:23Z

This fixes a bug where going read-only was taking longer than it should have due to copygc forgetting to check kthread_should_stop() Additionally: fix a missing is_kthread check in bch2_move_ratelimit(). Signed-off-by: Kent Overstreet

bcachefs: -EROFS doesn't count as move_extent_start_fail

2023-11-29T03:58:22Z

The automated tests check if we've hit too many slowpath/error path events and fail the test - if we're just shutting down, that naturally shouldn't count. Signed-off-by: Kent Overstreet

bcachefs: trace_move_extent_start_fail() now includes errcode

2023-11-28T22:18:24Z

Renamed from trace_move_extent_alloc_mem_fail, because there are other reasons we colud fail (disk space allocation failure). Signed-off-by: Kent Overstreet

bcachefs: Data update path won't accidentaly grow replicas

2023-11-26T02:48:42Z

Previously, there was a bug where if an extent had greater durability than required (because we needed to move a durability=1 pointer and ended up putting it on a durability 2 device), we would submit a write for replicas=2 - the durability of the pointer being rewritten - instead of the number of replicas required to bring it back up to the data_replicas option. This, plus the allocation path sometimes allocating on a greater durability device than requested, meant that extents could continue having more and more replicas added as they were being rewritten.

bcachefs: Make sure bch2_move_ratelimit() also waits for move_ops

2023-11-24T07:10:28Z

This adds move_ctxt_wait_event_timeout(), which can sleep for a timeout while also issueing pending moves as reads complete. Co-developed-by: Daniel Hill Signed-off-by: Kent Overstreet

bcachefs: bch2_moving_ctxt_flush_all()

2023-11-24T07:08:25Z

Introduce a new helper to flush all move IOs, and use it in a few places where we should have been. The new helper also drops btree locks before waiting on outstanding move writes, avoiding potential deadlocks. Signed-off-by: Kent Overstreet

bcachefs: Data move path now uses bch2_trans_unlock_long()

bcachefs: move: move_stats refactoring

2023-10-31T16:18:38Z

data_progress_list is gone - it was redundant with moving_context_list The upcoming rebalance rewrite is going to have it using two different move_stats objects with the same moving_context, depending on whether it's scanning or using the rebalance_work btree - this patch plumbs stats around a bit differently so that will work.
