    fuse: categorize fuse_get_req() · b111c8c0
    Maxim Patlasov authored
    The patch categorizes all fuse_get_req() invocations into two categories:
     - fuse_get_req_nopages(fc) - when caller doesn't care about req->pages
     - fuse_get_req(fc, n) - when caller need n page pointers (n > 0)
    Adding fuse_get_req_nopages() helps to avoid numerous fuse_get_req(fc, 0)
    scattered over code. Now it's clear from the first glance when a caller need
    fuse_req with page pointers.
    The patch doesn't make any logic changes. In multi-page case, it silly
    allocates array of FUSE_MAX_PAGES_PER_REQ page pointers. This will be amended
    by future patches.
