This will\nonly work for the circumstance where the pages in the cache correspond\n1:1 with the pages attached to an inode\u0027s page cache.\n\nThis is required for CIFS and NFS: When disabling inode cookie, we were\nreturning the cookie and setting cifsi-\u003efscache to NULL but failed to\ninvalidate any previously mapped pages. This resulted in \"Bad page\nstate\" errors and manifested in other kind of errors when running\nfsstress.
