I'm planning to add online label set/get support to xfs, and to do so I plan to re-use the existing btrfs ioctls, BTRFS_IOC_[SG]ET_FSLABEL We're still working out minor details on the xfs side, but I'd like to start the conversation regarding the new more generic interface ASAP, so here goes - patches to move the ioctls to the vfs and document them. (Other filesystems may wish to use this interface in the future as well) Thanks, -Eric
