| | | | | | | Found by aaron@ NOTE - I think we need a mount-point iterator just like we have NOTE - vfs_mount_foreach_vnode. (btw. why don't we use foreach_vnode in here?)
* Change the locking on the mountpoint slightly. Instead of using mnt_lockart2002-07-121-26/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to get shared locks for lookup and get the exclusive lock only with LK_DRAIN on unmount and do the real exclusive locking with flags in mnt_flags, we now use shared locks for lookup and an exclusive lock for unmount. This is accomplished by slightly changing the semantics of vfs_busy. Old vfs_busy behavior: - with LK_NOWAIT set in flags, a shared lock was obtained if the mountpoint wasn't being unmounted, otherwise we just returned an error. - with no flags, a shared lock was obtained if the mountpoint was being unmounted, otherwise we slept until the unmount was done and returned an error. LK_NOWAIT was used for sync(2) and some statistics code where it isn't really critical that we get the correct results. 0 was used in fchdir and lookup where it's critical that we get the right directory vnode for the filesystem root. After this change vfs_busy keeps the same behavior for no flags and LK_NOWAIT. But if some other flags are passed into it, they are passed directly into lockmgr (actually LK_SLEEPFAIL is always added to those flags because if we sleep for the lock, that means someone was holding the exclusive lock and the exclusive lock is only held when the filesystem is being unmounted. More changes: dounmount must now be called with the exclusive lock held. (before this the caller was supposed to hold the vfs_busy lock, but that wasn't always true). Zap some (now) unused mount flags. And the highlight of this change: Add some vfs_busy calls to match some vfs_unbusy calls, especially in sys_mount. (lockmgr doesn't detect the case where we release a lock noone holds (it will do that soon)). If you've seen hangs on reboot with mfs this should solve it (I repeat this for the fourth time now, but this time I spent two months fixing and redesigning this and reading the code so this time I must have gotten this right).
