围绕12版这一话题,我们整理了近期最值得关注的几个重要方面,帮助您快速了解事态全貌。
首先,Every WHERE id = N query flows through codegen_select_full_scan(), which emits linear walks through every row via Rewind / Next / Ne to compare each rowid against the target. At 100 rows with 100 lookups, that is 10,000 row comparisons instead of roughly 700 B-tree steps. O(n²) instead of O(n log n). This is consistent with the ~20,000x result in this run.

此外,The caller provides context and modifies the behavior of get_user_pages() via flags. Of particular interest is the FOLL_FORCE flag, which mem_rw() passes. This flag causes check_vma_flags (the access validation logic within get_user_pages()) to ignore writes to unwritable pages and allow the lookup to continue. The “punch through” semantics are attributed entirely to FOLL_FORCE. (comments my own)
最后,“The sooner such a plan is ready, the better,” the report concludes. “One never knows when an emergency will arise, and we must be prepared to break the glass.”
