https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=216087 Bug ID: 216087 Summary: NFSv4.1 client recovery from NFSERR_BADSESSION might starve recovery thread Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: rmacklem@FreeBSD.org Created attachment 178895 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=178895&action=edit Patch to give exclusive locker of nfsc_lock priority over shared lockers When the NFSv4.1 client is doing recovery from a server crash/reboot, the recovery thread "nfscl" must acquire an exclusive lock on the clientid (nfsc_lock). This patch gives exclusive lockers priority over shared lockers, so that the "nfscl" recovery won't be starved out (livelocked) by shared lockers. -- You are receiving this mail because: You are the assignee for the bug.
