From: Yichong Chen <[email protected]>
netfs_pgpriv2_copy_to_cache() marks the folio with PG_private_2 before
netfs_pgpriv2_copy_folio() appends it to the copy-to-cache rolling
buffer.
If the append fails, the folio is not queued for cache writeback, so
the PG_private_2 state and its reference must be released immediately.
Fixes: e2d46f2ec332 ("netfs: Change the read result collector to only use one
work item")
