If anyone has any objections, please let me know. ------------------ From: Hristo Venev commit 544576f0f05c4a759806acddfaaeb686f14fb4b0 upstream. The batch holds references to the folios (see `filemap_get_folios`, `folio_batch_release`), so we need to `folio_put` the folios we remove. Tested on v6.18.
