Here's a message I sent to nfs@lists.sourceforge.net this Friday: --quote-- xSubject: 2.6.0-test3-bk10-final regression getting out of hand xDate: Fri, 31 Oct 2003 21:48:51 +0100 As reported in: http://marc.theaimsgroup.com/?l=linux-kernel&m=106195494828814&w=2 I'm experiencing a serious NFS regression since 2.6.0-test3-bk10-final (bk-set determined now). Since that, along the road to 2.6.0-test9, something has gotten completely out of hand. cp -a /mnt/oden/etc . _2.6.0-test3-bk10_ 2 minutes _2.6.0-test3-bk10-final_ 3 minutes 47 seconds _2.6.0-test9_ 29 minutes 54 seconds Nothing has changed in hardware or setup, and the cp tests were done today. Not being a programmer I tried to delete individual patches in the bk-set, but couldn't find the exact breakage point. Erasing changes to: linux-2.6.0-test3-bk10/fs/nfs/dir.c No change. Erasing changes to: linux-2.6.0-test3-bk10/fs/nfs/nfsroot.c No change. Erasing changes to: linux-2.6.0-test3-bk10/include/linux/sunrpc/timer.h linux-2.6.0-test3-bk10/net/sunrpc/timer.c No change. Erasing changes to: linux-2.6.0-test3-bk10/net/sunrpc/clnt.c Doesn't compile. Erasing changes to: linux-2.6.0-test3-bk10/include/linux/sunrpc/xprt.h linux-2.6.0-test3-bk10/net/sunrpc/xprt.c Doesn't compile. Using TCP or DIRECTIO in -test9 makes no difference.
