Same as single_open(), but preallocates the buffer of given size. Doesn't make any sense for sizes up to PAGE_SIZE and doesn't make sense if output of show() exceeds PAGE_SIZE only rarely - seq_read() will take care of growing the buffer and redoing show(). If you _know_ that it will be large, it might make more sense to look into saner iterator, rather than go with single-shot one. If that's impossible, single_open_size() might be for you. Again, don't use that without a good reason; occasionally that's really the best way to go, but very often there are better solutions. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> |
