Mark Johnston <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #7 from Mark Johnston <[email protected]> --- I think the problem is in r363415. It converted some lockmgr code to use atomic_fcmpset instead of atomic_cmpset. The former can fail spuriously on LL/SC platforms, so a tryxlock operation can fail even when the buf is unlocked. lockmgr should take care to retry if fcmpset fails but returns the "expected" value. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
