A method, computer program product, and a computing system are provided for de-duplicating remote procedure calls at a client. In an implementation, the method may include generating a plurality of local pending remote procedure calls. The method may also include identifying a set of duplicate remote procedure calls among the plurality of remote procedure calls. The method may also include associating each remote procedure call within the set of duplicate remote procedure calls with one another. The method may also include executing a remote procedure call of the set of duplicate remote procedure calls. The method may further include providing a response for the remote procedure call of the set of duplicate remote procedure calls with the other remote procedure calls of the set of duplicate remote procedure calls.

De-duplicating remote procedure calls

Managing access control lists (ACLs) across replicated data repositories can include selecting, from a first data processing system, a controlled object and an ACL object bound to the controlled object, wherein the first data processing system is associated with a first user identity space, and creating, using a processor, a replicated version of the controlled object within a second data processing system associated with a second user identity space, wherein the second user identity space is different from the first user identity space. Managing ACLs further includes, creating, using the processor, a replicated version of the ACL object within the second data processing system and substituting, within the replicated version of the ACL object, an identity from the first user identity space with a selected identity from the second user identity space.

Maintaining access control lists in non-identity-preserving replicated data repositories

In a subject filesystem, the invention computer method use the filesystem's dentry trees for all file system objects not contained in a corresponding stacking filesystem. The invention method set the process environment to have a reliable inheritance of the stacking filesystem's root context to new processes and uses the subject filesystem's (VFSMNT, dentry) for most lookups. All lookup results are then with respect to the subject filesystem's roots.
