I'm not worried about other readdir calls invalidating the page. My concern is rather about the VM memory reclaimers ejecting the page from the page cache, and calling nfs_readdir_clear_array while we're referencing the page.
Wait, if nfs_readdir_clear_array can clear the page while somebody else has a refcount to it, what good is the refcount? Why is your .releasepage modifying the data on the page, instead of just the metadata in the struct page? -- All rights reversed -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
