fuse: add flag fc->initialized
Existing flag fc->blocked is used to suspend request allocation both in case of many background request submitted and period of time before init_reply arrives from userspace. Next patch will skip blocking allocations of synchronous request (disregarding fc->blocked). This is mostly OK, but we still need to suspend allocations if init_reply is not arrived yet. The patch introduces flag fc->initialized which will serve this purpose. Signed-off-by: Maxim Patlasov <mpatlasov@parallels.com> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
