Merge patch series "netfs: Miscellaneous fixes"
David Howells <dhowells@redhat.com> says:
Here are some miscellaneous fixes for netfslib.
(1) Clear PG_private_2 on copy-to-cache append failure.
(2) Fix handling of rolling buffer allocation failure in single-object
writeback. This is probably unnecessary with (4), but if we're only
writing to the cache, we can skip the write.
(3) Fix cleanup of readeahead folios if iterator preparation fails.
(4) Fix folio_queue allocation failure in writeback by adding a mempool.
This also improves request and subrequest allocation.
