Summary: Allow FUSE drivers to increase readahead setting. Details: FUSE drivers can set a max_readahead value in the fuse_init_out value. However, this value can currently only decrease the readahead setting from the default, which is set to VM_READAHEAD_PAGES in bdi_alloc(). Add a flag which causes the kernel driver to accept whatever max_readahead value the user provides in fuse_init_out. Note that read_ahead_kb_store() similarly allows users to set arbitrary ra_pages values.
