# Merge: 9977b1a71488 a62a8ef9d97d
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'virtio-fs-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse
#     
#     Pull fuse virtio-fs support from Miklos Szeredi:
#      "Virtio-fs allows exporting directory trees on the host and mounting
#       them in guest(s).
#     
#       This isn't actually a new filesystem, but a glue layer between the
#       fuse filesystem and a virtio based back-end.
#     
#       It's similar in functionality to the existing virtio-9p solution, but
#       significantly faster in benchmarks and has better POSIX compliance.
#       Further permformance improvements can be achieved by sharing the page
#       cache between host and guest, allowing for faster I/O and reduced
#       memory use.
#     
#       Kata Containers have been including the out-of-tree virtio-fs (with
#       the shared page cache patches as well) since version 1.7 as an
#       experimental feature. They have been active in development and plan to
#       switch from virtio-9p to virtio-fs as their default solution. There
#       has been interest from other sources as well.
#     
#       The userspace infrastructure is slated to be merged into qemu once the
#       kernel part hits mainline.
#     
#       This was developed by Vivek Goyal, Dave Gilbert and Stefan Hajnoczi"
