[PATCH] readahead: reset cache_hit earlier
We don't reset the cache hit count until after readahead does a successful readahead. This seems to leave a corner case open where we miss in cache, but don't restart the readhead right away. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
