[Qemu-devel] [PATCH 0/3] virtiofsd: add FUSE_INIT map_alignment field

[Stefan Hajnoczi]

The client must know the server's alignment constraints for FUSE_SETUPMAPPING
and FUSE_REMOVEMAPPING.  This is necessary because mmap(2)/munmap(2) have
alignment constraints and the guest may have a different page size from the
host.  The new FUSE_INIT map_alignment field communicates this information to
the client.

Stefan Hajnoczi (3):
  virtiofsd: sync up fuse.h Linux 5.1 header
  virtiofsd: add map_alignment to fuse_kernel.h
  virtiofsd: implement FUSE_INIT map_alignment field
