Christoph Hellwig 176042404e mm: add PSI accounting around ->read_folio and ->readahead calls ... PSI tries to account for the cost of bringing back in pages discarded by the MM LRU management. Currently the prime place for that is hooked into the bio submission path, which is a rather bad place: - it does not actually account I/O for non-block file systems, of which we have many - it adds overhead and a layering violation to the block layer Add the accounting into the two places in the core MM code that read pages into an address space by calling into ->read_folio and ->readahead so that the entire file system operations are covered, to broaden the coverage and allow removing the accounting in the block layer going forward. As psi_memstall_enter can deal with nested calls this will not lead to double accounting even while the bio annotations are still present.
