Subject: improve pagecache PSI annotations
Date: Sat, 10 Sep 2022 08:50:53 +0200 [thread overview]
Message-ID: <20220910065058.3303831-1-hch@lst.de> (raw)
Hi all,
currently the VM tries to abuse the block layer submission path for
the page cache PSI annotations. This series instead annotates the
->read_folio and ->readahead calls in the core VM code, and then
only deals with the odd direct add_to_page_cache_lru calls manually.
