If urgency does develop in the next couple of days, please let me know, and I will see what I can do about moving it to the v6.4 pile. I got this from "make run" (after merging with v6.3-rc3 as discussed earlier): make[1]: Leaving directory '/home/git/linux-build' 126 test(s) passed. This differs from your results, so please see below for the run.out file. (I see 126 instances of "[OK]".) But this from "make run-user": CC nolibc-test 124 test(s) passed The output of "grep -v "\[OK]" run.out" is as follows: Running test 'syscall' 18 chroot_root [SKIPPED] 43 link_dir [SKIPPED] Errors during this test: 0 Running test 'stdlib' Errors during this test: 0 Running test 'protection' Errors during this test: 0 Total number of errors: 0 Exiting with status 0 I am guessing is that this is because I am too cowardly to run this test with root privileges, but thought I should run it by you.
