The symptom was that sometimes file systems would occasionally not appear in output from 'df' or 'mount' if the system was busy. Resolution: - Make mount locks work somewhat like vm_map locks. - vfs_trybusy() now only fails if the mount is gone, or if someone is unmounting the file system. Simple contention on mnt_lock doesn't cause it to fail. - vfs_busy() will wait even if the file system is being unmounted. |
