Revision a7ba4bf5e7ff6bfe83e41c748b77b49297c1b5d9 authored by Linus Torvalds on 02 July 2015, 18:21:26 UTC, committed by Linus Torvalds on 02 July 2015, 18:21:26 UTC
Pull fuse updates from Miklos Szeredi: "This is the start of improving fuse scalability. An input queue and a processing queue is split out from the monolithic fuse connection, each of those having their own spinlock. The end of the patchset adds the ability to clone a fuse connection. This means, that instead of having to read/write requests/answers on a single fuse device fd, the fuse daemon can have multiple distinct file descriptors open. Each of those can be used to receive requests and send answers, currently the only constraint is that a request must be answered on the same fd as it was read from. This can be extended further to allow binding a device clone to a specific CPU or NUMA node. Based on a patchset by Srinivas Eeda and Ashish Samant. Thanks to Ashish for the review of this series" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse: (40 commits) fuse: update MAINTAINERS entry fuse: separate pqueue for clones fuse: introduce per-instance fuse_dev structure fuse: device fd clone fuse: abort: no fc->lock needed for request ending fuse: no fc->lock for pqueue parts fuse: no fc->lock in request_end() fuse: cleanup request_end() fuse: request_end(): do once fuse: add req flag for private list fuse: pqueue locking fuse: abort: group pqueue accesses fuse: cleanup fuse_dev_do_read() fuse: move list_del_init() from request_end() into callers fuse: duplicate ->connected in pqueue fuse: separate out processing queue fuse: simplify request_wait() fuse: no fc->lock for iqueue parts fuse: allow interrupt queuing without fc->lock fuse: iqueue locking ...
