[PATCH] splice: speedups and optimizations
- Kill the local variables that cache ->nrbufs, they just take up space. - Only set do_wakeup for a real pipe. This is a big win for direct splicing. - Kill i_mutex lock around ->f_pos update, regular io paths don't do this either. Signed-off-by: Jens Axboe <axboe@suse.de>
