getfsstat / nullsfs / automount bug?

2017-11-20 Thread Jamie Landeg-Jones
There appears to be a bug in the system call related to getmntinfo(3) / getfsstat(2) , when if the "automount" flag is set on "nullfs" mounts, it is not returned on a getfsstat "WAIT" call. The non-refreshed, non-blocking "MNT_NOWAIT" produces the correct result. I first noticed this when debugg

Loader.conf problem

2017-11-20 Thread Thomas Laus

head -r325700 to -r325997: problem locking/unlocking/ for (at least) amd64?

2017-11-20 Thread Mark Millard
Ever since I updated from -r325700 to -r325997 I've been having odd, non-repeatable, fairly rare problems on amd64. (I've yet to see if I get similar issues on other platforms.) I've reported a couple of panic for page faults in kernel mode in other list messages. But I'm also getting things like
