Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing data are disclosed. In some implementations, visual representations of files are generated for presentation in a backup user interface. The visual representations are generated from sparse file system metadata stored on the computing device, thus allowing faster navigating of the backup user interface. During a restore operation, the metadata can be used to retrieve the items from their physical storage locations. In some implementations, when the storage capacity of a backup storage device exceeds a threshold, the data for the N oldest backups are replaced with sparse file system metadata, which can be used to generate visual representations for presentation in the backup user interface.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for file system management. In one aspect, a method includes receiving a request at a kernel to perform a file operation on a particular file; identifying a flag bit associated with the file; invoking user space file handler to perform particular action when the flag bit is set; determining whether notification that action has been performed by file handler is received; and allowing the file operation on the file when notification is received.

Abstract: In an example implementation, a method includes receiving an indication to reclaim memory from a cache, the cache including a plurality of data buckets each configured to store one or more records and corresponding access bits. The method also includes selecting a data bucket from the cache, and processing the selected data bucket. Processing the selected data bucket includes determining access bits of the selected data bucket that are clear, and expunging data records corresponding to those access bits from the cache. Processing the selected data bucket also includes determining access bits of the selected data bucket that are set and do not correspond to records relevant to outstanding requests by a process utilizing the cache, and clearing those access bits. The method also includes repeating selecting and processing data buckets until a stop criterion is satisfied.
Abstract translation: 在示例实现中，一种方法包括接收从缓存回收存储器的指示，所述高速缓存包括多个数据桶，每个数据桶被配置为存储一个或多个记录和对应的存取位。 该方法还包括从高速缓存中选择数据桶，并处理所选择的数据桶。 处理所选择的数据桶包括确定清除的所选数据桶的存取位，以及从高速缓存中清除对应于这些存取位的数据记录。 处理所选择的数据桶还包括确定所选择的数据桶的访问位，其被设置并且不对应于利用高速缓存的进程与未完成请求相关的记录，并且清除那些访问位。 该方法还包括重复选择和处理数据桶，直到满足停止标准。

Abstract: This disclosure relates to service discovery using a dynamically configurable Bloom filter. According to some embodiments, various parameters of the Bloom filter may be determined by a first wireless device. The parameters may include a number of services advertised using the Bloom filter, a false positive rate of the Bloom filter, a set of hash functions used with the Bloom filter, and/or a size of the Bloom filter. The Bloom filter may be generated according to the determined parameters. The Bloom filter, along with some or all of the parameters of the Bloom filter, may be transmitted by the first wireless device. A second wireless device may use the Bloom filter as part of a service discovery process to determine whether or not a desired service is available via the first wireless device.
