The fix eliminated the KCSAN data-race report for this bug. It is yet to be evaluated what happens if tp->cur_tx changes between the test in line 4363 and line 4397. This test should certainly not be cached by the compiler in some register for such a long time, while asynchronous writes to tp->cur_tx might have occurred in line 4254 in the meantime.

To resolve this issue, execute folio_hstate(folio) under the protection of the hugetlb_lock lock, ensuring that folio_hstate(folio) does not return NULL.

[ Upstream commit eedf3e3 ] ACPICA commit 1c28da2242783579d59767617121035dafba18c3 This was originally done in NetBSD: NetBSD/src@b69d1ac and is the correct alternative to the smattering of `memcpy`s I previously contributed to this repository. This also sidesteps the newly strict checks added in UBSAN: llvm/llvm-project@7926744 Before this change we see the following UBSAN stack trace in Fuchsia: #0 0x000021afcfdeca5e in
