2023-06-23mm: rename invalidate_mapping_pagevec to mapping_try_invalidateMatthew Wilcox (Oracle)
We don't use pagevecs for the LRU cache any more, and we don't know that the failed invalidations were due to the folio being in an LRU cache. So rename it to be more accurate.

All users are now converted to use the folio_batch so we can get rid of this data structure. Link: https://lkml.kernel.org/r/20230621164557.3510324-11-willy@infradead.org Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2023-06-23net: convert sunrpc from pagevec to folio_batchMatthew Wilcox (Oracle)
Remove the last usage of pagevecs. There is a slight change here; we now free the folio_batch as soon as it fills up instead of freeing the folio_batch when we try to add a page to a full batch. This should have no effect in practice.

Remove a few hidden compound_head() calls by converting the returned page to a folio once and using the folio APIs. We also only increment the refcount on the folio once instead of once for each page. Ideally, we would have a for_each_sgt_folio macro, but until then this will do.

This wrapper for sg_set_page() lets drivers add folios to a scatterlist more easily. We could, perhaps, do better by using a different page in the folio if offset is larger than UINT_MAX, but let's hope we get a better data structure than this before we need to care about such large folios.

2023-06-23mm: pass nid to reserve_bootmem_region()Yajun Deng
early_pfn_to_nid() is called frequently in init_reserved_page(), it returns the node id of the PFN. These PFN are probably from the same memory region, they have the same node id. It's not necessary to call early_pfn_to_nid() for each PFN. Pass nid to reserve_bootmem_region() and drop the call to early_pfn_to_nid() in init_reserved_page(). Also, set nid on all reserved pages before doing this, as some reserved memory regions may not be set nid. The most beneficial function is memmap_init_reserved_pages() if CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled. The following data was tested on an x86 machine with 190GB of RAM. before: memmap_init_reserved_pages() 67ms after: memmap_init_reserved_pages() 20ms Link: https://lkml.kernel.org/r/20230619023406.424298-1-yajun.deng@linux.dev Signed-off-by: Yajun Deng <yajun.deng@linux.dev> Reviewed-by: Mike Rapoport (IBM) <rppt@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2023-06-23mm/gup: do not return 0 from pin_user_pages_fast() for bad argsJason Gunthorpe
These routines are not intended to return zero, the callers cannot do anything sane with a 0 return. They should return an error which means future calls to GUP will not succeed, or they should return some non-zero number of pinned pages which means GUP should be called again. If start + nr_pages overflows it should return -EOVERFLOW to signal the arguments are invalid. Syzkaller keeps tripping on this when fuzzing GUP arguments.

2023-06-23kasan,kmsan: remove __GFP_KSWAPD_RECLAIM usage from kasan/kmsanTetsuo Handa
syzbot is reporting lockdep warning in __stack_depot_save(), for the caller of __stack_depot_save() (i.e. __kasan_record_aux_stack() in this report) is responsible for masking __GFP_KSWAPD_RECLAIM flag in order not to wake kswapd which in turn wakes kcompactd. Since kasan/kmsan functions might be called with arbitrary locks held, mask __GFP_KSWAPD_RECLAIM flag from all GFP_NOWAIT/GFP_ATOMIC allocations in kasan/kmsan. Note that kmsan_save_stack_with_flags() is changed to mask both __GFP_DIRECT_RECLAIM flag and __GFP_KSWAPD_RECLAIM flag, for wakeup_kswapd() from wake_all_kswapds() from __alloc_pages_slowpath() calls wakeup_kcompactd() if __GFP_KSWAPD_RECLAIM flag is set and __GFP_DIRECT_RECLAIM flag is not set.

2023-06-23mm: compaction: skip memory hole rapidly when isolating migratable pagesBaolin Wang
On some machines, the normal zone can have a large memory hole like below memory layout, and we can see the range from 0x100000000 to 0x1800000000 is a hole. So when isolating some migratable pages, the scanner can meet the hole and it will take more time to skip the large hole. From my measurement, I can see the isolation scanner will take 80us ~ 100us to skip the large hole [0x100000000 - 0x1800000000]. So adding a new helper to fast search next online memory section to skip the large hole can help to find next suitable pageblock efficiently. With this patch, I can see the large hole scanning only takes < 1us.

2023-06-23workqueue: clean up WORK_* constant types, clarify maskingLinus Torvalds
Dave Airlie reports that gcc-13.1.1 has started complaining about some of the workqueue code in 32-bit arm builds: kernel/workqueue.c: In function ‘get_work_pwq’: kernel/workqueue.c:713:24: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 713 | return (void *)(data & WORK_STRUCT_WQ_DATA_MASK); | ^ [ ... a couple of other cases ... ] and while it's not immediately clear exactly why gcc started complaining about it now, I suspect it's some C23-induced enum type handlign fixup in gcc-13 is the cause. Whatever the reason for starting to complain, the code and data types are indeed disgusting enough that the complaint is warranted. The wq code ends up creating various "helper constants" (like that WORK_STRUCT_WQ_DATA_MASK) using an enum type, which is all kinds of confused. The mask needs to be 'unsigned long', not some unspecified enum type. To make matters worse, the actual "mask and cast to a pointer" is repeated a couple of times, and the cast isn't even always done to the right pointer, but - as the error case above - to a 'void *' with then the compiler finishing the job. That's now how we roll in the kernel. So create the masks using the proper types rather than some ambiguous enumeration, and use a nice helper that actually does the type conversion in one well-defined place. Incidentally, this magically makes clang generate better code. That, admittedly, is really just a sign of clang having been seriously confused before, and cleaning up the typing unconfuses the compiler too.
