- * Prewarm LFC cache to the specified state.
- *
- * Prewarming can interfere with accesses to the pages by other backends. Usually access to LFC is protected by shared buffers: when Postgres
- * is reading page, it pins shared buffer and enforces that only one backend is reading it, while other are waiting for read completion.
- *
- * But it is not true for prewarming: backend can fetch page itself, modify and then write it to LFC. At the
- * same time `lfc_prewarm` tries to write deteriorated image of this page in LFC. To increase concurrency, access to LFC files (both read and write)
- * is performed without holding locks. So it can happen that two or more processes write different content to the same location in the LFC file.
- * Certainly we can not rely on disk content in this case.
- *
- * To solve this problem we use two flags in LFC entry: `prewarm_requested` and `prewarm_started`. First is set before prewarm is actually started.
- * `lfc_prewarm` writes to LFC file only if this flag is set. This flag is cleared if any other backend performs write to this LFC chunk.
- * In this case data loaded by `lfc_prewarm` is considered to be deteriorated and should be just ignored.
- *
- * But as far as write to LFC is performed without holding lock, there is no guarantee that no such write is in progress.
- * This is why second flag is used: `prewarm_started`. It is set by `lfc_prewarm` when is starts writing page and cleared when write is completed.
- * Any other backend writing to LFC should abandon it's write to LFC file (just not mark page as loaded in bitmap) if this flag is set.
- * So neither `lfc_prewarm`, neither backend are saving page in LFC in this case - it is just skipped.
