wrt to the help files being installed multiple times, kevans already figured it out, but just to make it clear, the loader has some architecture specific help files but they also don't work.

Also, I just did a make world to test this patch (even though it's probably not fully correct) and there were no apparent problems apart from loader.help getting installed multiple times (once for all of the loader variants).

Just did a test booting in non-UEFI mode and then loaddev is set the same as currdev here. So the second problem seems to be specific to the EFI loader.

Call swapon(2) after trimming, but before closing the trimming fd.

Probably not safe to start trimming the swap device *after* the kernel has been told to start using it for swapping (even if the window is probably small).

sigsys_gmail.com updated the diff for D16998: making cmp faster, especially on special files (and speed up wc -l too while at it).

Don't mind me, just enjoying my very fast cmp (and wc -l).

sigsys_gmail.com updated the diff for D16998: making cmp faster, especially on special files (and speed up wc -l too while at it).

Some cleanups, added a wc test case, fixed a cmp test case, fixed some wc logic that made it avoid its (already existing) fast path on STDIN.

Ok. I just read the comment. Apart from the bit twiddling hack the code looks straightforward enough. Maybe it’s not fair to ask this, but it would be comforting if there were regression tests attached to this change.

> If you care about 32 bit performance perhaps have an ifdef LP64 around the type used.

After testing on an old Pentium 4, turns out the line counting algorithm was slower than the naive implementation because operations on 64 bits long longs were slow. Changing it to use 32 bits long makes it faster but only 1.5 times or so faster.
