I have queued this for the v6.5 merge window, thank you! 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.
Thanx, Paul
