[Virtio-fs] [PATCH 0/2][V2] virtiofsd: Do not setup mapping read-write always

[Vivek Goyal]

Setup mapping either read-only or read-write depending on what client
has asked for. Also open file O_RDONLY for read-only mapping (and not
O_RDWR). Otherwise files always get copied up on overlayfs.

Vivek Goyal (2):
  virtiofsd: During setup mapping, open file O_RDWR only if needed
  virtiofsd: No need to promote O_WRONLY to O_RDWR
