+BULK INODE PAGE UNCACHE
+-----------------------
+
+A convenience routine is provided to perform an uncache on all the pages
+attached to an inode. This assumes that the pages on the inode correspond on a
+1:1 basis with the pages in the cache.
+
+ void fscache_uncache_all_inode_pages(struct fscache_cookie *cookie,
+ struct inode *inode);
+
+This takes the netfs cookie that the pages were cached with and the inode that
+the pages are attached to. This function will wait for pages to finish being
+written to the cache and for the cache to finish with the page generally. No
+error is returned.
