...but I do agree with your comment. The patch I meant to refer to (see revised title) does not appear in the 2.5.x tree either. Have we BTW been shown any numbers that support the alleged benefits? I may have missed those...A while ago yes - on very big SMP boxes. Its no big problem to me since I can just back it out of -ac
just curious, because I use this patch since early 2.4.20, are there any reasons to 'back it out of -ac' for you? anyway I totally agree that the NFS issue pointed out by Trond should be addressed ... TIA, Herbert
