syzbot hit kernel BUG at fs/hugetlbfs/inode.c:532 as described in [1]. This BUG triggers if the HPageRestoreReserve flag is set on a page in the page cache. It should never be set, as the routine huge_add_to_page_cache explicitly clears the flag after adding a page to the cache. The only code other than huge page allocation which sets the flag is restore_reserve_on_error. It will potentially set the flag in rare out of memory conditions. syzbot was injecting errors to cause memory allocation errors which exercised this specific path. The code in restore_reserve_on_error is doing the right thing. However, there are instances where pages in the page cache were being passed to restore_reserve_on_error. This is incorrect, as once a page goes into the cache reservation information will not be modified for the page until it is removed from the cache. Error paths do not remove pages from the cache, so even in the case of error, the page will remain in the cache and no reservation adjustment is needed. Modify routines that potentially call restore_reserve_on_error with a page cache page to no longer do so. Note on fixes tag: Prior to commit 846be085 ("mm/hugetlb: expand restore_reserve_on_error functionality") the routine would not process page cache pages because the HPageRestoreReserve flag is not set on such pages. Therefore, this issue could not be trigggered. The code added by commit 846be085 ("mm/hugetlb: expand restore_reserve_on_error functionality") is needed and correct. It exposed incorrect calls to restore_reserve_on_error which is the root cause addressed by this commit.

Originally the addr != NULL check was meant to take care of the case where __kfence_pool == NULL (KFENCE is disabled). However, this does not work for addresses where addr > 0 && addr < KFENCE_POOL_SIZE. This can be the case on NULL-deref where addr > 0 && addr < PAGE_SIZE or any other faulting access with addr < KFENCE_POOL_SIZE. While the kernel would likely crash, the stack traces and report might be confusing due to double faults upon KFENCE's attempt to unprotect such an address. Fix it by just checking that __kfence_pool != NULL instead.

In a debugging session the other day, Rik noticed that node_reclaim() was missing memstall annotations. This means we'll miss pressure and lost productivity resulting from reclaim on an overloaded local NUMA node when vm.zone_reclaim_mode is enabled. There haven't been any reports, but that's likely because vm.zone_reclaim_mode hasn't been a commonly used feature recently, and the intersection between such setups and psi users is probably nil. But secondary memory such as CXL-connected DIMMS, persistent memory etc, and the page demotion patches that handle them (https://lore.kernel.org/lkml/20210401183216.443C4443@viggo.jf.intel.com/) could soon make this a more common codepath again.

HWPoisonHandlable() sometimes returns false for typical user pages due to races with average memory events like transfers over LRU lists. This causes failures in hwpoison handling. There's retry code for such a case but does not work because the retry loop reaches the retry limit too quickly before the page settles down to handlable state. Let get_any_page() call shake_page() to fix it.

We've noticed occasional OOM killing when memory.low settings are in effect for cgroups. This is unexpected and undesirable as memory.low is supposed to express non-OOMing memory priorities between cgroups. The reason for this is proportional memory.low reclaim. When cgroups are below their memory.low threshold, reclaim passes them over in the first round, and then retries if it couldn't find pages anywhere else. But when cgroups are slightly above their memory.low setting, page scan force is scaled down and diminished in proportion to the overage, to the point where it can cause reclaim to fail as well - only in that case we currently don't retry, and instead trigger OOM. To fix this, hook proportional reclaim into the same retry logic we have in place for when cgroups are skipped entirely. This way if reclaim fails and some cgroups were scanned with diminished pressure, we'll try another full-force cycle before giving up and OOMing.

When placing pages on a pcp list, migratetype values over MIGRATE_PCPTYPES get added to the MIGRATE_MOVABLE pcp list. However, the actual migratetype is preserved in the page and should not be changed to MIGRATE_MOVABLE or the page may end up on the wrong free_list. The impact is that HIGHATOMIC or CMA pages getting bulk freed from the PCP lists could potentially end up on the wrong buddy list. There are various consequences but minimally NR_FREE_CMA_PAGES accounting could get screwed up.

Due to the change about how block layer detects congestion the justification of commit 8fd2e0b5 ("mm: swap: check if swap backing device is congested or not") doesn't stand anymore, so the commit could be just reverted in order to solve the race reported by commit 2efa33fc ("mm/shmem: fix shmem_swapin() race with swapoff"), so the fix commit could be just reverted as well. And that fix is also kind of buggy as discussed by [1] and [2].

Function init_resources() allocates a boot memory block to hold an array of resources which it adds to iomem_resource. The array is filled in from its end and the function then attempts to free any unused memory at the beginning. The problem is that size of the unused memory is incorrectly calculated and this can result in releasing memory which is in use by active resources. Their data then gets corrupted later when the memory is reused by a different part of the system. Fix the size of the released memory to correctly match the number of unused resource entries.

When the schema fixups are applied to 'select' the result is a single entry is required for a match, but that will never match as there should be 2 entries. Also, a 'select' schema should have the widest possible match, so use 'contains' which matches the compatible string(s) in any position and not just the first position.
