2023-12-05slub: Update frozen slabs documentations in the sourceChengming Zhou
The current updated scheme (which this series implemented) is: - node partial slabs: PG_Workingset && !frozen - cpu partial slabs: !PG_Workingset && !frozen - cpu slabs: !PG_Workingset && frozen - full slabs: !PG_Workingset && !frozen The most important change is that "frozen" bit is not set for the cpu partial slabs anymore, __slab_free() will grab node list_lock then check by !PG_Workingset that it's not on a node partial list. And the "frozen" bit is still kept for the cpu slabs for performance, since we don't need to grab node list_lock to check whether the PG_Workingset is set or not if the "frozen" bit is set in __slab_free(). Update related documentations and comments in the source.

2023-12-05slub: Rename all *unfreeze_partials* functions to *put_partials*Chengming Zhou
Since all partial slabs on the CPU partial list are not frozen anymore, we don't unfreeze when moving cpu partial slabs to node partial list, it's better to rename these functions.

2023-12-05slub: Optimize deactivate_slab()Chengming Zhou
Since the introduce of unfrozen slabs on cpu partial list, we don't need to synchronize the slab frozen state under the node list_lock. The caller of deactivate_slab() and the caller of __slab_free() won't manipulate the slab list concurrently. So we can get node list_lock in the last stage if we really need to manipulate the slab list in this path.

2023-12-04slub: Delay freezing of partial slabsChengming Zhou
Now we will freeze slabs when moving them out of node partial list to cpu partial list, this method needs two cmpxchg_double operations: 1. freeze slab (acquire_slab()) under the node list_lock 2. get_freelist() when pick used in ___slab_alloc() Actually we don't need to freeze when moving slabs out of node partial list, we can delay freezing to when use slab freelist in ___slab_alloc(), so we can save one cmpxchg_double(). And there are other good points: - The moving of slabs between node partial list and cpu partial list becomes simpler, since we don't need to freeze or unfreeze at all. - The node list_lock contention would be less, since we don't need to freeze any slab under the node list_lock. We can achieve this because there is no concurrent path would manipulate the partial slab list except the __slab_free() path, which is now serialized by slab_test_node_partial() under the list_lock. Since the slab returned by get_partial() interfaces is not frozen anymore and no freelist is returned in the partial_context, so we need to use the introduced freeze_slab() to freeze it and get its freelist. Similarly, the slabs on the CPU partial list are not frozen anymore, we need to freeze_slab() on it before use. We can now delete acquire_slab() as it became unused.

2023-12-04slub: Prepare __slab_free() for unfrozen partial slab out of node partial listChengming Zhou
Now the partially empty slub will be frozen when taken out of node partial list, so the __slab_free() will know from "was_frozen" that the partially empty slab is not on node partial list and is a cpu or cpu partial slab of some cpu. But we will change this, make partial slabs leave the node partial list with unfrozen state, so we need to change __slab_free() to use the new slab_test_node_partial() we just introduced.

2023-11-22slub: Keep track of whether slub is on the per-node partial listChengming Zhou
Now we rely on the "frozen" bit to see if we should manipulate the slab->slab_list, which will be changed in the following patch. Instead we introduce another way to keep track of whether slub is on the per-node partial list, here we reuse the PG_workingset bit. We have to use the atomic set_bit() and clear_bit() variants and change slab_unlock() to bit_spin_unlock() because when cmpxchg is not available and PG_lock is used, there may be concurrent operations on the two bits. Thanks to Mark Brown for reporting a hang and testing of a previous version where the non-atomic operations were used.

2023-11-13slub: Change get_partial() interfaces to return slabChengming Zhou
We need all get_partial() related interfaces to return a slab, instead of returning the freelist (or object). Use the partial_context.object to return back freelist or object for now.

2023-11-13slub: Reflow ___slab_alloc()Chengming Zhou
The get_partial() interface used in ___slab_alloc() may return a single object in the "kmem_cache_debug(s)" case, in which we will just return the "freelist" object. Move this handling up to prepare for later changes. And the "pfmemalloc_match()" part is not needed for node partial slab, since we already check this in the get_partial_node().

2023-11-10spi: Fix null dereference on suspendMark Hasemeyer
A race condition exists where a synchronous (noqueue) transfer can be active during a system suspend. This can cause a null pointer dereference exception to occur when the system resumes. Example order of events leading to the exception: 1. spi_sync() calls __spi_transfer_message_noqueue() which sets ctlr->cur_msg 2. Spi transfer begins via spi_transfer_one_message() 3. System is suspended interrupting the transfer context 4. System is resumed 6. spi_controller_resume() calls spi_start_queue() which resets cur_msg to NULL 7. Spi transfer context resumes and spi_finalize_current_message() is called which dereferences cur_msg (which is now NULL) Wait for synchronous transfers to complete before suspending by acquiring the bus mutex and setting/checking a suspend flag.

Fix to check the tracepoint event is not valid with $retval. The commit 08c9306fc2e3 ("tracing/fprobe-event: Assume fprobe is a return event by $retval") introduced automatic return probe conversion with $retval. But since tracepoint event does not support return probe, $retval is not acceptable. Without this fix, ftracetest, tprobe_syntax_errors.tc fails; [22] Tracepoint probe event parser error log check [FAIL] ---- # tail 22-tprobe_syntax_errors.tc-log.mRKroL + ftrace_errlog_check trace_fprobe t kfree ^$retval dynamic_events + printf %s t kfree + wc -c + pos=8 + printf %s t kfree ^$retval + tr -d ^ + command=t kfree $retval + echo Test command: t kfree $retval Test command: t kfree $retval + echo ---- So 't kfree $retval' should fail (tracepoint doesn't support return probe) but passed it.
