Most of them concerned performance, Peter Zijlstra stumbled over it when working unrelated changes and I believe there was an actual bug report. Oh, Andrew Morton also complained about duplicating code from mm/readahead.c. It is just not worth it. On flash media like usb sticks, readahead will make things go slow - very slow. On spinning disks, readahead may be a win, but this is definitely not the place to add it. Signed-off-by: Jörn Engel --- Reading git-diff-tree failed
