https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219988 Mateusz Guzik <mjg@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mjg@FreeBSD.org --- Comment #2 from Mateusz Guzik <mjg@FreeBSD.org> --- The lock at hand is initialized with RM_SLEEPABLE, i.e. sleep is permitted. It probably is desirable to turn it into a non-sleepable lock, but I don't think it's a high priority (and right now I don't even if this is feasible). The patch at hand is definitely incomplete even for sysctl_add_oid. strdup = also performs M_WAITOK. --=20 You are receiving this mail because: You are the assignee for the bug.=
